I'm on birth control but I had sex without a condom many times, but only once did I get ejaculated into, which was 7 weeks ago. Lately I've found myself not able to eat, I'm hungry but whenever I try to eat after taking a few bites I want to vomit. Even smelling food or thinking about it makes me nauseous most times. I picked up food today after barely eating for two days and I could only finish a little. I skipped my period last month and I tried to get it this month, I ended up taking a week of my pills but then stopped.. a week or so later there's still no sign of a period. I'm also currently treating myself for a yeast infection so I'm not sure if that could be something that would interfere. I'm just wondering if it's worth buying a pregnancy test, I'm planning on buying one tomorrow.
