Weird discharge before period

Sarah

My period is due in three days. Yesterday I wiped and there was a small red spot of what looked like bloody mucus so I thought my period was starting. Since then there has been absolutely nothing when I wipe besides some white discharge.

My boobs are sore and I’ve had migraines and slight cramps but that generally happens with my period.

Ovulated around the 12th or 13th based on OPKs. Anyone experienced this before? What came of it?
