My SIL was able to get pg 2 years ago (1st Try!) but lost her baby at 10w due to s subchorionic bleed

She has been suffering from infertility since. She has had a water sono...the dye test...clomid...etc. But just can't get pg. And her DH checks out a-ok
She is seeing a new RE and he is concerned about a fibroid she has in her uterus. It is messering .8cm big. Does anyone know if having a fibroid can keep you from GETTING pg?
She is going in for an MRI next week so the RE can get more info on the fibriod...he wants to remove it.
I have always had a pretty easy time getting pg...just not staying pg

so I am not sure about all of this. I am just worried about her, KWIM. We talk alot and she comes to me of advise b/c I am very open about my losses. She lost her baby a week before I had my 2nd m/c.
