Blood clot (subchorionic hemorrhage) at 6 week ultrasound - IVF Pregnancy

I was having brown spotting around 5w3d that turned into bright red blood the next day. I immediately put myself on bed rest. The red bleeding subsided into light brown spotting again. Yesterday at 6 weeks, we went in for my first ultrasound and everything looks normal, except I have a small blood clot inside my uterus. The doctor called it a subchorionic hemorrhage and that he sees them fairly common. I asked if my placenta was attached and he verified it was. He told me that it doesn’t matter what I do - if I take it easy or carry on regularly with life - my pregnancy will progress if it’s meant to. Overall I am happy, but still a little nervous. I’ve had 3 miscarriages before and we want this baby so much! We conceived this baby with IVF, and I read that subchorionic hemorrhage is fairly common in

IVF and FET pregnancies. For those of you who have had IVF, have you experienced this too, and what was your outcome?
