5 weeks/6 weeks

So I am having some spotting but it’s only when I wipe. It’s not every time I wipe but every now and then. The color is brown/pink. And it’s not a lot. I am also on 200mg vaginal progesterone nightly. As anyone ever experienced this and everything be okay? I did go to the ER Friday because I was paranoid and had an ultrasound done and HCG blood work. They saw gestational sack and yolk sack on ultrasound and my HCG level was 15,000. Help! I didn’t have any of this spotting and stuff before my miscarriages!!
