Fibroid and pregnancy

So, nobody told me that I might have pains bc of my fibroid, but from yesterday evening I feel pains which are on and off just in the place where I have my fibroid (it's located on the outer side of the uterus and I can find it as a tough oval form). Earlier I just felt some random pains mainly when I was on a long walk in that area, but now it's hard to walk and stay stil and it's getting worser in the end of the day. I'm 28 weeks and I really hope I can handle these pain to deliver my baby not too early...
