i think i am going nutsoo!

Well.. Last month on the 8th I went to my doctor to get back on bc. He put me on somthing I have never been on before. I tried it for like 2 days and I didnt like it because it made me dizzy.II had a period around the 19th.. Well after I stopped taking it Me and My husband had sex multiple times and we have never used protection. Now My face is breaking out, I have lower back pains, I wake up in the middle of the night and dont go back to sleep, I was in the shower and I just vomitted out of the blue, I have a big increase in discharge, and my nipples are very sensitive. I know thats a lot of symptoms but maybe im overreacting. I took a test yesterday afternoon because I really couldnt wait and it was neg.! I dont know what to do.. I know its too soon but should I be feeling like this yet?
