Ive been trying to get pregnant and we have been having unprotected sex since Jan 1.I was due to start my period jan 21 and I just started.Is there any chance i could still be pregnant?Last time we had unprotected sex was sunday.We have done it many times since the 1st.We really want a baby and Im heartbroken that I just started.This would make me have started 2 days early which i never do im usually a week or so late.could I be pregnant or is that chance gone?
