need help

So i managed to get pregnant while nursing after needing infertility treatment with my first. It seems that i have clotting issues cuz i had a sch with my son and had my first scan at 5 weeks today that showed a yoke and egg sack but again a huge sch with my son it was tiny and resolved this one is huge! she put me on strict bedrest and told me to stop nursing. i dont feel good about this pregnancy and i have a 5 month old i cant be on bed rest cuz i have no help. I definitely dont want to stop nursing if theres a high risk of loss which she indicated there is. Anyways im on progesterone and seriously just wanting to end all of this grief now instead of just waiting for the inevitable anybody know if stopping the progesterone could end the pregnancy? ps i was not trying to concieve i was actually told birth control was unnecessary due to our history.
