Pinkish discharge

Ne

Hello ladies, I am currently about 6 or 7 weeks prego, this is my second pregnancy, I am experiencing discomfort in my lower back and sometimes in my pelvis a bit of cramps, but I’ve noticed I keep getting this pinkish discharge when I wipe, today when I went to the bathroom I notice more or this discharge but with a bit of blood clots tiny ones, could this be a sign of an ectopic pregnancy? I went to a ultrasound yesterday to see if the baby is in the right place but couldn’t see much I’m going back in two weeks, does anybody else experience something like this and is doing fine? Please help!
