4 weeks and 5 days bleeding

Mi

Ok so im 4 weeks and 5 days I started spotting pink blood 2 days ago and went to the er . They were about to do ultrasound and I started bleeding red blood not alot just very light bleeding, they couldn’t see anything on the ultrasound except for my cyst on my ovary unfortunately again , because im so early. Got my RhoGAM shot again, Well my hcg levels were at 29 he said to come back in 2 days to see if they double. I go home and bleeding gets a little heavier but no clots and definitely not like my other two miscarriages. I went back today and hcg levels are at 41 so it didn’t double but it did go up and im just spotting and slight cramping now so technically I bled for 2 days like a period. My miscarriages i bled for almost two weeks. So they are going to do progesterone test on me and ill know Monday of what’s exactly happening to me and the baby. Anyone else experienced this and had a healthy baby in return if so please tell me what happened.
