Hey everyone, I'm in need of some help.
Well, my fiance and I decided to have sex for the first time on December, 27th and though I was on birth control, I was taking an antibiotic for a sinus/head cold. I had switched birth control too, and I was having breakthrough bleeding all Decemeber but when it came time for my period, I didn't get it. I thought it was because of all the bleeding I'd done earlier. And then when I started my new pact in January I didn't get my breakthrough bleeding, nor did I get my period, which I am suppose to be going through right now. I threw up once in January, but it was just that one time. I had a bit of spotting in January, it was there when I went to the bathroom, but then the next time I went, I didn't have it anymore. I kept taking my birth control and my fiance and I had sex quite a bit since December too.
I've been getting these sick feelings, like I could throw up but I never do. I've been extremely tired too, and my stomach just feels...different. But I've taken two different pregnancy tests and both have said I wasn't pregnant, I'm not sure what to do. I don't have the money to go to the doctor to get a blood test done, and I don't want to keep taking my birth control if I am pregnant because I don't want to harm my baby.
Any advice?
