Good night everyone! It's almost 40 weeks now, and around 10:30 PM today I had dull pains in my lower abdomen, like during my period, and my stomach felt flat. This happened about three times with a 25-30 minute interval, but now the pain and these sensations have subsided, but there's a slight twinge in my lower back, I can't tell if it's starting or just a false alarm??‍? I had this recently, but then it went away ? I don't know what to think anymore ? And by the way, for a couple of days, the discharge has been very thick?? (sorry for the details)
