I had sex while ovulating on the 20th this month hoping for baby number 2.I have been tracking my ovulation very close. I am to start my period on the 3rd of june. I have been feeling full since the 20th as well as nauseous. I am having slight pelvic pain as in cramps but like I said I am not to start until the 3rd of june. The upper part for my belly is hard. Could this possibly mean I could be pregnant
