Help!

Hi guys! Need some help here, got my BFP on 2/29. A week later, last friday to be exact went to the ER cramping and bleeding. Told me that I was probably miscarrying, ultrasound didn’t show anything. Bloodwork said I was about 4 weeks (hcg 347) Went back on Sunday to repeat everything hcg measured at 299 still bleeding not cramping. I was sure I was miscarrying. Fast forward to yesterday, took a pregnancy test, I know that it takes a while for everything to go down to 0. But the test was even darker than the first 4 I took the week prior and Im no longer bleeding. Has anyone had this happened? Baby dust to all! ❤️
