WELL ACCORDING TO AN OVULATIONG CALCULATOR WE HAD SEX EVERYDAY THAT I MIGHT HAVE BEEN FERTILE. 23-29 OF SEPTEMBER. I AM NOT ON ANY BC. ABOUT 2 MONTHS AGO I GOT MY MIRENA IUD TAKEN OUT CAUSE IT WASNT WORKING OUT FOR ME. AFTER I GOT IT TAKEN OUT ME AND MY BF HAD A TALK ABOUT WHAT TYPE OF BC I SHOULD GO ON. HE SUGGESTEDED NATRUAL.
