Well I was on depo the bc shot for about 2 years and I read a lot that many people got pregnant on the shot and some didnt even know because when they took the test somehow the depo would effect the results and say they werent pregnant and then they found out that they actually were pregnant... And I had sex right around the time I was switching from depo to the pill, and because this pill also prevents me from getting my period im not sure if im pregnant or not because ive had a few symptoms but it says those same symptoms can be caused from birthcontrol so im not sure if im pregnant or not and im scared that I wont know because I have no way of knowing if I had a missed period and if these symptoms are from being pregnant or from birthcontrol unless I take a test and ive been really afraid to go and buy one
