I miscarried Feb 20. That day my hug was less than 5. When can I expect to ovulate?

Do u mean hcg? Assuming your periods are regular, you should ovulate about 14 days after the first day of your next period.
4-6 weeks . Sorry to hear about the miscarriage. The first cycle usually comes four to six weeks after the beta HCG hormone has completely resolved. Ovulation is two weeks before that, it is very hard to time things the first moth after miscarriage .
