COULD I BE PREGNANT?

I have PCOS I've gotten pregnant naturally one time without any medicine, but unfortunately my pregnancy ended in miscarriage. My period can sometimes be irregular but usually I don't spot often and if I do my period immediately come on I may spot a few times then *BAM* aunt Flo is here. I've been having sex with a friend almost 1 year. He's pretty fertile as he has 7 children which he takes care of. He's a wonderful father and wants a baby together. We have a lottt of sex and yes he ejaculates in me. On the 3rd I noticed some mucous with a pink tint but only when I wiped. The next minute it was gone, later I used the bathroom and wiped and it was light a bright red. Then it went away a few hours later my I was spotting a dark brown then it went away. I only spot for that one day which never happens, before that I was having period like cramps but after spotting no cramps. But I have noticed the past two days ice been reallyyy tired and need a nap but I believe that's just exhaustion. My last period was 5/22/19 I spotted 6/3/2019
