hi there , this is my third pregnancy , and i have had the same thing its horrible, and worse is not many people understand the annoying pain it is.
I went into labour at 28 weeks after having my show, 2min apart contractions they were thankfully able stop, with nefedipine- horrible stuff. and bed rest .
luckily i havent dilated so im happily 32 weeks at home where i belong lol..
im quite content to wait untill bubs is ready now, if u just try to relax , drink lots, and limit intercourse you will find it should settle down alot, good luck and i wish u the best for your bubs arrival.
