Sex and period??

Hello everyone,

So I just wanted advice/thoughts on my story. So i had chemo this year from January to March. I got back to school this year and my periods haven’t been coming because obviously my chemo affected my system. My doctor said that even though I got my period monthly from like May to August he was expecting my period to be regular after a year.

I took a rapid pregnancy test yesterday and it came out negative with no faint lines at all. I also had a blood HcG test early October and it came negative too. I have only had sex three times and they were all with a condom and when my partner came he took it out even though he was wearing one. (He’s also big for me which may have been a reason it hurt in the beginning until lubricated enough)

Today I got some brown egg white feel-discharge after peeing and there was a some light red too but mostly like medium brown. What does this mean or what do you think? I appreciate any comments
