Can you conceive during your period?

This sounds like a really dumb question, but hear me out. I have PCOS and my period is out of control. I’ll bleed for 3 months or more in a row and then stop for a day or two and start up again for a long while over and over. Well it’s been gone since Saturday and I was wondering if since I bleed SO often and so long if I could conceive while I’m bleeding or if that’s impossible?
