Hi, I'm 18 years old and have been with my boyfriend for about 4 years. For the past couple of years I have been on and off of birth control and recently I decided to get off of it completely due to the harsh symptoms I experienced while taking it. I got my last period on May 13th and it lasted about 6 days. Since then, I have had unprotected sex a few times and he pulled out. (I am aware this is not a birth control method). I have never had a regular period schedule so I am not sure how late I am, but I have yet to get my period or experience any of the pre menstrual symptoms that I usually do a week prior to getting it. As for pregnancy symptoms, I haven't had any nausea/fatigue/sore breasts etc. but I have noticed that I began having some heart palpitations which I have never experienced before. The only other explanation I can find for this is that a few weeks ago I got my wisdom teeth out and was prescribed a pretty high dose of Tylenol 3 and ibuprofen and I thought maybe my body was sensitive to the caffeine in the t3's since I am not a coffee drinker. It has now been 3 weeks though and i can't imagine my heart palpitations would last this long from something I stopped taking this long ago. I completely understand this was irresponsible and I will be taking measures to prevent pregnancy after this, but I am just curious if this is a sign that I might be pregnant.
