Threatened miscarriage

Im 7 weeks 5 days. This is my third pregnancy. I went in Monday for bleeding, got diagnosed with threatened miscarriage. The doctor in the Er said my cervix was dilated, I was bleeding (obviously), and that the baby was not measuring correctly, but levels match baby growth. The baby has a heartbeat, but she told me I had a 90% chance of a miscarriage. I went back wed. Thought I had a miscarriage due to a clot I had passed. Tmi. The doctor on duty that morning did an exam, says my cervix is now closed, the bleeding is light. Also, the clot apparently was "nothing" to worry about. And he looked everything over from Monday, thinks the bleeding is from my placenta "coming loose around the edges". Still threatened miscarriage and on bedrest. But things are looking up. Appointment on Monday with my ob. Fingers crossed that this little one is healthy!!! ❤❤ anyone else had anything like this happen?? I've never experienced this before. 😔
