Do you think?

This may or may not be a direct question, I just need some opinions here. Last March I had a miscarriage (naturally) I offically stopped bleeding Mrach 10th. I had some bleeding on and off from April 9th through the 12th. This month I had a somewhat "normal" period from the 18th until the 23rd. Last night I had with my fiance and we used a condom like we have been since the miscarriage. Our problem is that last night, to our dismay, the condom broke, and we didn't realize it until it was too late. I'm usually very regular and I was wondering if I could already be back on track with my ovulation dates. I hope I am because that would mean it would turn out that I didn't get pregnant. But I'm not sure, what do you think? I don't want to get pregnant now, my doctor says that getting pregnant so soon after a miscarriage usually ends in another miscarriage. Should I just wait and see?
