Me and my boyfriend have been dating for 1 yr and we recently started having sex. I started taking the pill 19th of feb. I used this brand of birth control for 2 months successfully, and then was forced to switch to a cheaper Brand of birthcontrol. I asked the pharmacist and he said my body will pick up right where it left off with the other brand. I started a new brand on the 16th of April! We had sex on the 27th and we did not use protection. Then on the 28th I didn't take my pill until 6:45 am. I take it at 11:30 pm. My birth control has 4 lighter pills where I should have my period. I took the 2nd pill last night and havent started my period yet. Do you think I am pregnant? Let me know if you need anymore information. Please help me.
