Cd 39 and no period

Negative urine pregnancy test, they are the internet Cheapos. No sign of AF coming. Still have a cold. Started to get heartburn after dinner last night, couldn't even finish it. Trying to wait a couple more days to test again.  This is fun, not lol. Did have a weird cycle this last time. Spotted for three weeks after period had ended. So maybe I will just be late because of this weird one.
