So I had a miscarriage back in February. And just started a birth control pack this past month. The pharmacist told us it should be effective right away, but through further research, it's typically effective after 7 days. We had unprotected sex on day three of my pills. And according to this app, it was also the day before my ovulation. I know you are also more fertile after a miscarriage. I have been so hungry, having to pee a lot, and moody for the past week. I also had slight cramps yesterday, which felt like implantation cramps. I'm only on the second week of birth control. Could these be medicine symptoms or could I be pregnant again? lol
