After miscarriage..

I had a miscarriage at the beginning of the month and the bleeding lasted for 3 weeks. I’m still waiting on my period, which according to the app is due next week, although I’m not sure how accurate that is right now. These last few days I’ve had some very, very light sporting. We have been intimate since the miscarriage after receiving an all clear from the doctor. I’m thinking it may have been too soon. A few questions for those who can relate..

- how long did it take for your period to return?

- did we maybe not wait long enough?

- is this normal?

- is there any other advice you can offer?

Thanks!
