Potential late positive after Cd37?

La

Currently CD37, tested negative Hpt on both CD27, CD32. Usually have a 28-30 day cycle. Had a missed miscarriage resulting in a erpoc on 13th jan, normal period in feb on the 15th, then nothing.. haven’t been overly sexually active but do remember ewcm around cd14 and did it on Cd15 and cd17.

Any thoughts? Anyone gotten late pregnancy positives?

Am going to call doctor for blood test next week but asking for advice
