Bl ending from my bum at 15 weeks

Hi all I’ve never experienced bleeding from my bum it did scare me and I’m wondering if I need to go and check to see if everything is alright. It wasn’t a small amount it was an amount that scared me to the point I had to check so many time to see where the bleeding was coming from but I think it’s from my bum. I called my friend and she said it’s normal.

Has anyone experienced bleeding from your bum during second trimester??
