Bleeding heavily + clots at 15 weeks!! ๐Ÿ’”

Zee โ€ข Mama to a beautiful baby girl named Lana ๐Ÿ‘ผ๐Ÿป๐ŸŽ€
This started Thursday.. I stayed in the hospital Fri under observation, as blood was soaking whenever I stand up. Left Sat and bleeding decreased with no clots.. but still there. Today again, I started bleeding heavy and clots just like when it all started! ๐Ÿ’”
Last time I did ultrasound was Saturday, and the tech did detailed ultrasound and baby was fine and perfect. I am so scared to lose it.. this is my first pregnancy (I don't cramp.. but the blood is very very worrisome and scary..) I'm devastated.. anyone had anything similar? ๐Ÿ˜ž
