Bleeding from vagina when going for a poo , 2worrying

I'm due on my period in a couple of days and have been having bad PMS (i stopped my mini pill a few weeks before laay period so unsure I'd hormones are still getting back to normal ) on sayurdayb I strained really hard for a bowl movement (sorry tmi), and the after I noticed a bit of bleeding from my vagina (definitely came from here I checked ) yesterday when went toilet it was fine today I have just been to the toilet and the same things had happened but this time I wasnt really straining I had a smear test done a couple of months ago which was clear and I had a baby 9 months ago I did atop taking the mini pill before my last period due to it giving my anxiety but we have had protected sex and i took a pregnancy test just incase as well which was negative I'm just wondering if anyone has experienced anything similar ? I have health anxiety so always think the worst
