So I have been having signs of pregnancy for about a month and I thought I might be pregnant but then I got my period but it was four days early and I'm still having signs of pregnancy. My breast are sore, I'm very bloated, get very nauseous in the afternoon and some smells trigger it also. I'm having bad headaches that I never had before, and my body just feels very different. And I did have some spotting shortly after I ovulated. Could be pregnant?
