13 weeks pregnant and dot of blood when I wipe

Alex

So this is my first pregnancy and yesterday I noticed a very small dot of blood when I wiped after going pee... so I’ve been checking it every time I go but I’ve only seen it about 2 or 3 times, it’s kind of pink/red I just want to know if it’s normal or if I should call my doctor??

I’ve been cramping but I thought it was normal
