Fibroid and pregnancy...?

i am now 19 1/2 weeks pregnant. my first ultrasound at 7 weeks showed a small fibroid. my 18th week ultrasound showed the same fibroid only slightly bigger.has this happened to anyone? should i worry? what is going to happen to my baby or myself? am i going to bleed to death during labor? i know that might sound strange but i worry about these things.

It's not strange to worry at all!! I have quite a fibroid history and am still scared at this moment. 2 1/2 years ago, I had 6 fibroids removed from the outside of my uterus with a pretty major surgery. The doctor told me to "go make babies" because everything would be fine. I got pregnant Dec. 07, during ultrasounds, 3 smaller fibroids were found inside the uterus this time. I miscarried at 8 w 4 d and the dr. was pretty sure it was due to the largest of the 3 fibroids.
Well, I was due to have surgery June 2nd to get it removed so we could try to get pregnant. Four days before the surgery, I found out that even though we were very careful about protection, I was pregnant again! Ultrasounds show the fibroid has shifted position and is no longer hanging down in the uterus--a real miracle! I will be 8 weeks tomorrow, and so far, the heartbeat is great, the growth is on target, I feel completely different and have all the symptoms this time and the doctors think this pregnancy is going well so far.
Fibroids do grow a tiny bit faster due to hormones when you're pregnant, but most babies will grow and push right around them, so I think at 19.5 weeks, you should be fine at this point. You won't bleed to death giving birth, but they CANNOT remove it anytime during pregnancy or right after--if they try, the uterus can cause a hemmorage.
So basically, it's just an annoyance for you right now--they usually arent' cancerous or even painful unless they are left to grow huge. Nothing you can do but focus on your pregnancy, and sometime after the baby comes speak with a specialist about removal options. Fibroids happen to many many many of us--you're not alone!
Good luck--you're just about 1/2 way there!
