For Birth Control "I started this birth control my freshman year. I gained 10 lbs after starting this birth control, which I didn't mind because I was underweight, so it was good for me to gain the weight. I had no real problems with Necon, except every month, a week before my period, I got super emotional and had a lot of mood swings and got lower back cramps. After four years of taking Necon, I was starting to get extremely nauseous the last two weeks of the pack every month, so I just recently switched to a new birth control to try to get rid of the nausea. Overall, I really liked this birth control, it was easy to take and didn't have terrible side effects."

For Birth Control "I've been taking Necon 1/35 for almost 2 months now, and so far, I have experienced acne (which I've never had before), weight gain, breast growth (I was already a double D before), and crying spells. I think the worst is the weight gain and crying spells. This medicine has helped tremendously with my irregular heavy periods, though. I now have shorter periods and only once a month. I'm going to continue taking this for another month, and then I may consult my doctor."

For Birth Control "Okay, so I have been taking Necon for 9 months because of heavy cramping and long periods. The first couple of months were fine. I was just always emotional and sometimes had a bad attitude. The last month, I have been kind of depressed and having anxiety attacks. It didn't come clear to me that it was the pills until my friend stated that was once her side effect. I have put on a couple of pounds, and I am now able to fill out a complete D cup (unfortunately), and my acne isn't as bad as it was. It's a 50/50 good product."

For Birth Control "I have used Necon 1/35 for almost 5 months. I take the pill because my periods were heavy and painful. For the first 2 months, I had no problems, I had normal, short periods and nothing else. But for the last 3 months, I have had no period at all (100% sure I'm not pregnant), weight gain, and anxiety attacks. I guess the only good thing I can say about this pill is that I have no period whatsoever."

For Endometriosis "The Necon 1/35 works great for my endometriosis. In conjunction with the laparoscopy that I had, it has really kept the severe pains away. Now all I feel during menstruation is discomfort. And my periods are extremely light. No more heavy pads and 7-day long cycles. My cycles have been longest 3 days and only require a liner. On the negative side... I had clear porcelain skin. From the very first day of the pill, I began getting 3 little bumps between my eyes. After 3 months, my face looks like a pizza pie with every single topping on it. I have a breakout on every section of my face. Like another reviewer stated, I also gained 10 lbs. But like her, I am (was) underweight, so I definitely don't mind."

For Birth Control "I've been on Necon for about 5 months now. It's made my hormonal acne clear up wonderfully. I still have hyperpigmentation on my cheeks, but all the active cysts and zits have disappeared. During the first three months, my period came during the placebo week and was very light. During the fourth month, I was spotting the whole week before the sugar pill week and experienced no bleeding during my sugar pill week. My breasts have gone up a size, and I experienced 0 weight gain. I just switched insurance companies, and my new pharmacy switched me over to Nortrel, which I'm extremely nervous about because I haven't read the best reviews about Nortrel. Necon was absolutely wonderful for me!!"

For Birth Control "Necon 1/35 was my first birth control. I had no complaints. No weight gain, acne was less severe. I still had a pimple here and there, but nothing too problematic. During the week of the sugar pills, I had my period, and my period was lighter but still like clockwork. I’m currently on a new birth control (Deblitane), and I’m not sure I like it since it has no sugar pills. I was put on Deblitane because the nurse who prescribed it to me believed that my blood pressure is out of control when it really isn’t. I’d prefer the Necon."

For Birth Control "I have only been on Necon for a month and a half, but it has already started causing problems. I have a horrible time sleeping now, and I am eating a lot more than I used to. I haven’t weighed myself recently because I’m afraid to see how much weight I’ve gained in such a short amount of time. Also, on my placebo week in the first month, I had a very weird and scary experience that at the time I thought was a mini-stroke. I suddenly got really dizzy, and my vision was blurry, and I couldn’t move or speak for a minute. I have never had that happen to me before. It was absolutely terrifying. I’m going to be switching pills soon. The only good thing I can say about this is that it has helped my mood swings, and my periods are lighter and shorter so far."

For Birth Control "I recently just stopped taking Necon because of my terrible experience with it. I only took it for about 3 months, but it made my periods very irregular, I would have spotting on and off two weeks before my period, and it caused me to gain 10 pounds. I thought I was getting fat but had no change in my diet. I also have severe period cramps, and this does not help with them at all. I do not recommend this product."

For Birth Control "I'm giving this Necon 1/35 a rating of 3/10 only because I didn't get pregnant and didn't get a period. But this drug made me gain 20 lbs in 2 months with no lifestyle change, and I was extremely sensitive to the sun, which my doctor did not warn me about. I have olive complexion, almost never burn... spent 1 day outside in FL on a partly cloudy day and ended up with horrible sunburn. My skin was melting off my body, it was terrible."

For Birth Control "I was on this for about 3 years. This summer I was getting really depressed and my anxiety was at an all-time high before I would get my period. My doctor put me on antidepressants and wanted to monitor me. After the summer was over, I felt like I had symptoms of hormonal imbalance. Random light cramps during any week that I wasn’t on my period. Headaches, acne flare-ups, brittle and weak nails, my hair seemed to fall out more often, weight gain, tired all the time, longer periods. I think my birth control has stopped working for me. Let’s just hope I’m not pregnant, lol. After my next period, I’ll be taking Yazmin instead. Necon was fantastic while it lasted."
