Recurrent losses

I’m having my 5th loss in the span of a year. I have a 2 year old conceived with no issues. I’m 30. But now MC at 7 weeks in sept, 2nd trimester loss in February with d&e, followed by back to back early losses - 4+6 loss in June, 4+2 loss in July and now I’m at 5+2 and waiting to miscarry (hcg declining). This last one I started 200mg of progesterone orally at 3dpo. I don’t even know what to do now. I clearly get pregnant easily but nothing is sticking. I’m so defeated. I am seeing a RE but have been told it is bad luck so far. I am worried about ashermans or some type of scarring. Anyone have any words of wisdom or similar stories with success?
