I had misccariage 5 weeks and this is second misccariage 4 months ago how many days to start ovulation? And can I get pregnancy immediately please help me because I need to have baby so much thank you

It can take some time for your cycles to become regular again, or they can be regular soon after a miscarriage. If you have been having periods, odds are great that you have also been ovulating. The miscarriage itself won't necessarily prevent you from becoming pregnant soon after, but some suggest giving yourself a bit of time first. It is quite individual.

Keep in mind that even if you became pregnant very quickly before, it can naturally take some months before becoming pregnant again.
