10 days late??

Alicia

So my husband and I had sex 3 days before my period was suppose to start. I have not had any pregnancy symptoms or PMS symptoms. I took a pregnancy test at 7 days late and I was negative. So for the past 2 days I’ve started discharging this brown “pre-period” discharge as well as a little bit of pre period blood...not enough to mess up my panties. I’m still not experiencing any cramping or symptoms. Has this happened to you??
