So I had my period last month and I am ovulating right now and I just haven’t felt right since Sunday. Tired, nauseated, cramps, bloated. I am ovulating right now, supposedly. I didn’t know if it was possible to have my period and end up pregnant my grandma says she did but i didn’t know if that was maybe implantation bleeding? But she had it with her 3rd kid, so I think she would know the difference. Should I test? Any thoughts?
