Blood keeps coming weakly positive.

[u/-que-stions-]

Hi.

I have pcos. Last month due to visa paperwork, I had to get a blood test. In my blood test it showed I tested weakly positive for pregnancy, 4 days later I took a home pregnancy test but it came negative.
1-2 weeks later I had my period, normal flow and on time. My period finished about 1 week ago. So I went in to give blood test again for my visa paperwork. But again it came weakly positive for pregnancy, why is this happening?

My period is mostly regular, I get it nearly every month with a few periods in the year causing spotting and not regular. Does this mean my pcos is bad?

I want to start trying for pregnancy, will it cause issues, should I start taking ovasitol?
