Bleeding lightly/spotting after bowel movement?

Okay so I’m 5+2 and I’ve caught on to the fact that for the past week, every time I have a bowel movement I spot. The spotting is def from my vagina and no where else. I’ll wipe before my BM and there’s nothing, then I’ll immediately wipe after my BM and it’s either pink or brown. I do not push hard to avoid strain, I just let it run it’s course. Anyone else? Did everything turn out okay? It makes me think I’m having a MC every time this happens!
