Hey ladies. Does anyone know if it's possible to implant a day before period is due? Husband and I been trying to conceive for 4 years and last month my doc put me on letrozole to help ovulate. Not sure if I did because when I was suppose to do my labs I had covid. A day before my period was due It was light pink only when wiping and watery. I have been having some cramping and fatigue. I tested this a.m and it was negative. I'm going to retest in a week if my period doesn't show. Just curious if it's possible to implant a day before period and if anyone has had this happen before?
