Blood clot at 8 weeks ....

Paige
Hello! I had a blood clot at 8 weeks about 1 week ago and my doctor sent me to get a sonogram. The ultrasound tech said she saw a small bleed which she said was from my placenta attaching to the uterus wall. Has this happened to anyone else ?! I've had a lot of issues during this pregnancy already (I have 2 other children) thanks!
