I’ve been going crazy trying to figure out what’s going on but I’m on birth control pills and I take them at the same time every night and I’m sexually active. My period (or at least that’s what I think it is) came on the 6th and this is what it’s been like from the 6th until now. My period usually comes on a week and a half later are usually really really heavy and only last around 4 days. They usually come with really bad cramps as well but this time I had cramps but they were minor. I’ve been having consistent headaches and have been lightheaded and had changes in my blood pressure recently which all of this is new. Does anyone have any idea what it could be. I’m thinking there is s chance that I could be pregnant but idk. I got out on antibiotics like 3 weeks ago and I was taking them when I was taking my BC not knowing that the antibiotics could mess with my BC. Any information will help. I took a cheap pregnancy test but it came back negative. I was told to wait a couple more weeks to get more of an accurate read because it could be too early to tell. A couple days before this is was a pink orange color.
