Blood clot!!! 21 weeks

Tabby22

So today after heaving bleeding and an ultrasound. I found out that I have a 4cm blood clot in my cervix. My obgyn called to tell me that she is talking to 3 radiologists and that 2 of them are saying opposite things. One is saying that this blood clot is fine and the other is saying that he is concerned about it. (Havnt heard back from #3 yet.) They will be discussing this over the weekend and my doctor will get back to me on monday. I really want more information. Any of you delt with anything like this before. (Ps it's not a subchronic hematoma) please help!!
