Ruf- well it could be. I actually lost mine last week whilst I was already a patient in hospital. And I am only 24weeks tomorrow, so was a little worried. Mine was a like that as well, but the blob was about the size of a twenty cent piece. Luckly I could actually show them right there and then. I too had lots of BH, and they were very painful- but that pain also had alot to do with the cyst i was told. The doctors and midwives told me not to worry to much as Ive had no contractions or water breaking. There apparently is no risk of infection until your waters break. So i am keeping mt legs and fingers crossed that bubs don't come to early.
