Hey. Im 18 and I recently had unprotected sex with my boyfriend. I have these birth control pills called Lutera. I had started the pills at 12 a.m on thursday and we had unprotected sex, twice, that thursday around 6 p.m. The next day we had unprotected sex multiple times and i took my pill at 12 once again. The day after that we had sex, unprotected, and I accidently took my pill thirty minutes late. The next day we had unprotected sex once. It was before 12 a.m and he was leaving so I didn't take the pill. He ejaculated in me every time. So now, in the present, its been about a week since the intercourse I told you about. I feel sore and have had bad cramps.I have a cold that feels like the flu. Also my gums bleed now. I took a test yesterday and it was negative (probably too early to tell). Please tell me if your sure I'm pregnant or not..and if your not, tell me when i should take another pregnancy test or go to the doctor? thanks..
