Long Cycle,Tested Early,Anxious

Raven
I have a long cycle 32-34 days. I tested last week And had it confirmed by the doctors office. Everything came back positive but I'm still not actually due for my period until end of this week. A couple months ago I had a chemical pregnancy and I had positive HPTs but my period came anyways exactly when it was supposed to. I'm worried my upcoming period will force a miscarriage. It's terrifying and I can't find any information on it either way. Does anyone have any experience with this? Am I freaking myself out over nothing? 4+2 today.
