Well, last month I started my first pack of birth control pills. Two days before I started taking my pills (when I was on my period) me and my boyfriend had sex in a pool but he pulled out. (i am 100% sure he did). Then, I had a sinus infection the first week of the pack and was taking antiobiotics. The questions is my period was a brownish color this month and it was very very light. I think the first day I had to wear a pad but after that it was very light. It lasted about three days. But before I started taking them my period was always short and light but not brown. I was just wondering if this is normal for being on bcp's for the first time? Other things to consider is that I am on yasmin and I was affected by hurricane katrina and had to evacuate, so do you think the stress would cause that as well?
