Spotting after BM

Hi ladies,

I’ve spotted a few times this pregnancy so far, talked to my doctor and there isn’t really a reason for it but it’s always after straining from a BM (super constipated 😒) but it’s definitely coming from the front and not my backside. Has anyone had this and had a normal pregnancy? I’m about 6 weeks and ultrasounds have looked normal so far, no cramping or anything.
