Fibroid during pregnancy

i got a 7cm by 7cm fibroid :"( found out when went for first transvaginal ultrascan at 6weeks.. doc said just ignore it, and remove it (if it is still there) after delivery. one of my friends had a 10cm one, and it disappeared after she gave birth, so im praying the same thing will happen to me too! i did experience a few times of extremely sharp stabbing pains on my lower right abdomen, but gynae said that is more possibly round ligament strains. not sure if the pain is caused by the fibroid. before preg, im someone that always had menses cramp (quite severe type that i will always take 1day mc if i got period)
