first month trying since miscarriage. Any advice?

I just had my first period since my miscarriage in December (12.29). I wasn't trying last time but it's left a pretty big void & now me and my bf have decided to try! :) I had a lot of CM & was intimate before, on & after ovulation. According to the app I'm now 5dpo. I had some period like cramping last night while I was at the gym. What do you think my chances are?
