Hi. I've been taking Trinessa lo birth control pills (28) for almost two whole packs. I am now on my third day of inactive pills and am expecting my breakthrough bleeding tomorrow morning like it was last month. Sadly, I don't think it's going to come. I've been taking my birth control pills everyday, at the same time. But my boyfriend and I have been doing risky behaviors lately without a condom: dry humping naked for a couple minutes in different positions, Rubbing genitals and attempting penetration. He has NEVER ejaculated during these acts. But I know pre ejaculate can cause conception as well. I'm 17 years old and I'm trying to be responsible (I haven't even had sex yet) I am having almost every early pregnancy symptom, even my veins on my breasts have become more vibrant which is freaking me out. Could I be pregnant?
