We’re trying again after having a miscarriage and I’m really hoping everything works out this time🤞🏽 I’m 3dpo and we had sex almost every day of my fertile window and twice the day before ovulation, I did LH tests and track my bbt so I know I ovulated for sure. I just want to know already and I’ve read that you can get a positive test sooner than normal if you’ve conceived shortly after a miscarriage. How soon should/can I start testing?
