RPL tests

Hey, I'm 33yrs Young (😊) & recently had my 3rd MC in the last year so my Dr has now said we must look into what's going wrong, I've had blood tests yest at my surgery & I'm being referred to the gyne dept at my local hosp so just waiting to hear from them & waiting on blood results, feeling anxious & slightly hopeful but mostly anxious!😟 wondered if anyone could tell me what these tests involve & any similar (happy) stories to tell me, I need cheered up. Thanks ladies X
