Hi darl, I had it with both of mine right from the word go, with my DS it never led anywhere other than numerous trips to emergency throughout the pregnancy.

With my DD I ended up getting contractions at 21wks which led to me losing some of the plug, but after that I just got constant BHs until 37wks when prelabour kicked in (the contractions from irritable uterus were pretty much the same as prelabour in intensity and duration for me) and they found I was 1-2cm dilated (I never even dilated or stated to efface prior to being induced with my DS), then I had 3 weeks of constant prelabour before they broke my waters the morning of the day my DD was born where I was 2cm dilated before they broke my waters and 3cm right afterwards.
Sometimes the irritable uterous can help, other times it won't.

Hope you get to hold your bub in your arms soon
