I miscarried at the end of january, i had a blighted ovum. since then i feel like i have not ovulated. is there something i can do?

See a specialist: You should have ovulation return in about a month after a miscarriage. There are reasons for no ovulation, including the tests you are using are incorrect. Check your bbt, OPK and then your doc can also look at ultrasound and hormone levels in some cases to make a diagnosis. Failing to ovulate is usually an easy problem to correct. Best wishes.
