Subchorionic hematoma?!

I had my ultrasound at Thursday due to bleeding, they managed find the cause which was a subchronic hematoma. The baby was measuring pretty much bang on, with a good heartbeat.

I have bleed quite a bit today with a clot too, is this normal? After the clot bleeding has slowed down, pretty much stopped. I didn't get much explained to me, they put me on progesterone to give me a helping hand.

Sorry for tmi I have got a picture for the size, just wanted to no if its normal as I've never had one before, I did some research and I no clots can come about.
