The last time I had my period was probably on the 23rd of August, I don't really remember. Or even earlier.

My period is always irregular. I had anal sex 2 weeks ago, and 2-3 days later, I started getting blood discharge when i wiped. This lasted about 3 days, with one day where it was slightly heavier, enough to fill a whole pantyliner.

Is this my period?

Following this was brown discharge, that lasted about 2 days.

It is now 2 weeks in, and I have had no symptoms of pregnancy.
please help!
