Fibroid pressing against the womb in pregnancy.

Hi all! I am currently going to 13 weeks. Dr told me that one of my fibroids (4.6 cm) is pressing against the womb and there is a high chance of miscarriage and it will hinder the baby’s growth. I also experiencing fibroid pain but I am allergic to all painkillers. I would love to know other mummies experiences on this and if there’s anything I could do to ease the pain? Thank you so much😊
