Okay so I take Loestrin 24. I have for a couple years now. My period is light and usually on time, and I get it when I'm supposed to. My boyfriend and I do have sex and not use condoms but he usually pulls out. I am horrible about taking it on time and am very irregular when taking it. (I know bad) but when we last had sex was 4 weeks ago I want to say. I was supposed to get my period over a week ago and took a test and it came out negative. So I don't understand why I missed my period! Also I stopped taking the next pack after I missed it hoping it would come but didn't.. Should I continue on my next pack? I don't know what to do! I'm not having any other signs of being pregnant aka sore boobs, feeling nauseous, etc...
