I think another loss

Jessica

I was a week late so took a test three days ago was positive so took a digital two days ago and it was positive. Called dr since I have lost two already they sent me to get bloodwork done and I was at 30 which isn’t bad since I knew what day I ovulated so technically I am two weeks 3 days. Then today started spotting so they had me go get a rhogam shot and now bleeding!!! Smh why I this happening?? Anyone have any ideas honestly I need some thoughts.
