I had unprotexted sex dec 3rd and a few days later I started feeling funny, sore breats, tingly nipples, smell everything, bloated feeling in my lower stomach and some weird cramping and I took a test of the 15th, I know it was a little too soon but it came up negative and it didn't feel right. Now all my symptoms went away expect I wake up in the middle if the night naseous but go back to sleep and mu breats feel a little weird. My period is very regular, I get it the 20th. Is it all in my head??????
