Is this normal ? Had sex yesterday he finished inside and I fell asleep so idk if it could be that. Yesterday my cm was watery and heavy as it had been for about about 4 days up until today I noticed it was thick and clumpy. Is this the start of a yeast infection, or could semen cause this ? Nipples have been burning for two days…is pregnancy a possibility? We do the do every two days after I get off of my period so the first day we had was about 11 days ago. Cervix is still high and medium firmness.
