My boyfriend and I have been trying to conceive. June 22nd, 24th, 26th and 27th we tried. The tricky part is I don't keep track of my period. I usually get it late/early in the month. Would it be best to wait until around the 14th of July? (Which is 17 days after the last time.) What is the rule of thumb, if there is any? Some people say wait two weeks, 17 days and some even say 37 days. It's all confusing. I know for sure I had my period before June 6th, if that helps any.
