Thank you all for replying. I called the Dr's office again yesterday and they told me to go to L & D. They monitered me for awhile and everything seemed to look normal; no contractions, fetal heartbeat ok. They did an internal exam, and they think i have a small polyp that's growing again on my cervix. They think that might have just gotten irritated. They put me on pelvic rest until Monday just to make sure the spotting goes away..whew..what a relief ..
