I miscarried in November at 6 weeks. My doctor told me we could start ttc after I had my first regular period (post miscarriage bleeding) to allow my body to get back in a cycle. We ttc in December, but no BFP. This month I started tracking with ovulation strips and got my peak at CD 11. I’m definitely not an expert, but I wouldn’t be discouraged. You may just need to let your body to have more time to recover.
