Bleeding at 5w1d post 5d FET

I’m just so devastated. Started bleeding tonight. With Very very light intermittent twinges, not even cramps. How could this be after two wonderful betas this week. First at 4w3d of 1295 and on Thursday at 4w5d of 3255. Why is this happening to me! I’m just dying inside. After five miscarriage this was our first attempt at IVF with PGS and Endometrial receptivity testing. We did it all to give us the best chances. I can’t stop crying. We see doctor tomorrow for ultrasound and beta. 😭
