Hi bradandjane, i have several fibroids and they haven't been an issue with either of my kids. At last check they were between 5 and 8cm, so not big enough to warrant any further action.

My mum on the other hand had huge problems with hers, after her 3rd child (me!) they started growing and wrapped themselves around her urethra causing constant kidney infections. She ended up needing a hysterectomy because of them, but she never had any problems conceiving. Also, this is absolute worst case, when they where removed they were absolutely huge too! I think she said they filled an entire bucket with them.
