I'm 34 weeks and for the last few days I constantly have a similar feeling to when I'm about to start my period. Not really distinctive period pains as such, just a crampy, uncomfortable sort of feeling in my cervix and lower stomach. So much so that I keep half expecting to see blood when I wipe after going to the toilet. This is my second baby and I don't remember this at all first time round, until after I'd lost my mucus plug at 40 weeks and was about to go into labour. Just checking I'm not about to go into premature labour? Is this common in the mid-third trimester?
