So I'm in a really confusing situation. I switched my birth control about 6 weeks ago, I've never missed a day just been late taking them there were a few days I threw up after taking them and just now found out that makes them pretty much inactive. I've been skipping my periods since it's summer and I've been going to a lot of events. About 2 weeks ago I started getting really nauseous, fatigued, headaches, sore breasts, and I had a little bit of brown blood one day when I wiped then nothing. I took a pregnancy test about a week or so ago and it came back negative. I've still been feeling all of those symptoms and now certain smells are making me sick. Could I be pregnant and just have tested too early before?
