Advice please!

Hello!! I had a miscarriage back in October, as I’m sure you can all guess..... it was the most awful time of my life. I want a baby more than anything in the world!! And I am praying for my time to come. Well a couple weeks after the miscarriage I got my period back. It was pretty heavy and lasted about 6 days. Anyone with a similar experience, after the first period will your second one come at about the same time it usually used to? Just wondering because we have been TTC again and I’m hoping I will be able to tell if af is late or if I should just expect me period to be all whacked up and coming at different times due to circumstances? Any advice will help my racing mind!
