I went to the doctors, and they found I have a large cyst blocking my cervix it is just a little bigger than a golf ball... They could not explain the popping sensation, but they have told me now I will not be able to give birth naturally and will have to have a c-section. I have struggled with cysts since I hit puberty and the doctors were hoping pregnancy would make this a little better but this is the 3rd cyst they have found in my pregnancy, it is a little dissapointing that I cant deliver normally. I am just hoping I have a healthy baby at the end of it all. Thanx 4 your replies.
