Should I be okay or go back on BC for a while?

I’ve posted this once before about a month ago but since then I’ve had family join the app (that’s why I’m anonymous). I just want to see if I get different answers this time.

My husband and I are long distance for the time being. We had 3 MCs within a year the last one being last March. We get to see each other for two weeks starting April 3. Right now my predicted period is supposed to start March 24. My cycle used to be like clockwork but since my three consecutive MCs I’ll start a few days early and a few days late. I’m trying to figure out if I should go on BC so make my cycle start a little later so that I can make sure we’re together during my fertile week. I’m not exactly sure when I ovulate. It just makes me nervous that I could start a few days early and miss my fertile week. Also, any advice for how to best prepare myself. I just bought pregmate ovulation strips and a bbt thermometer. Sorry just looking for some reassurance. This is the last chance we get to try until the end of 2020 😕

If you read the whole think I appreciate it. Thank you for any advice.
