I recently lost my virginity and I have obviously been continuously sleeping with my boyfriend.. I am on the pill but we don't use a condom. I have had problems in the past with my pills not being effective... but anyway it was time for my period last month and I noticed it started a bit later than usual {only 2 days but that is weird for me considering I am on the pill} Also my period was very light, like I was barely spotting. So I decided just to be safe I should probably take an at home test, mainly because most of the females in my family had periods the first few months of their pregnancies.. So i took two tests one early in the week and one later.. even though I was told that my horomones we just screwed up because it was the first time I had, had sex. Both tests were negative. But this month rolled around and I still only spotted.. I've noticed a change in my appetite, and my breasts having been growing out of control.. I am not sure if this is just hormones or if its possible I am pregnant.. my boyfriend and i talked about it before but after the test came back negative we kind of just stopped worrying about it.. I want to calll the doctor and get checked out but because I am new to the whole situation I just want some elses opinion. And I'm worried if I am pregant what will the fact that I have been taking the pill all this time do to a baby??

Thanks so much in advance.. like I said I'm new to this and I'm kind of freaking out a little.
