I put my period dates into this site to see my best days to BD. So I just remembered I had this saved on my phone. I know the gender thing is probably total bull, but it would still be really cool if I do end up pregnant to see if the gender thing did work, even if it was a coincidence, still pretty funny! So, I tried to follow the dates, only I didn't get a chance to BD on the 21st, but did on the 22nd and 23rd.
