Anyone else experience this ??

I found out may 30th i was pregnant excited but also nervous called the dr office. They got me in for blood work on the 31st. My Hcg was @33. Then i began spotting dark brown which turned into a heavier bleeding over Saturday and early sunday. But not quite period amounts of bleeding. I went back in on the 3rd my Hcg was @101, they did an ultrasound as well and didnt see anything. ( not sure if thats normal at 4w 4d based on LMP) so i went back in on the 5th for a blood draw and my Hcg was @260 progesterone was 4.9 . I have been spotting on and off since finding out i was pregnant . Has anyone else had similar experience what was the outcome ? Also this is pregnancy #9 i have 2 children. Had 2 ectopics and then 4mc . And now im pregnant again but scared to get my hopes up. Hoping for our rainbowbaby !!!
