Normal?

Ok, so I ended up having to take Plan B on October 24 (ovulation day). Ever since I randomly spotted and the last 3 months i have literally had my period every two weeks and sometimes spot while having sex. Has anyone else had this happen after taking plan B? Yes, if this continues I plan on going to a Gyno, but with shutdown and a lung condition... I can’t really be out in public. Not sure if BC could help level out hormones or if something could be seriously wrong. Or am I just over freaking out. It’s really messing up my sex life!!

Side note: yes I did take a couple PTs (a month apart) and both came out negative. Also took 2 in November and those were negative as well.
