I have just experienced weird contractions, felt like my whole bump tightening, it lasted about 30s, had them twice in 5 min. I don't remember having things like that with previous pregnancies, they were very strong and made me cry. My bump is big, baby painfully active and now this. Having midwife appointment on Wednesday will mention it. Also feeling very heavy between my belly and chest, it's like felling high and then relaxed down...it's hard to describe. I'm not out of breath, not sure it could be something to do with blood pressure, with all midwife and hospital checks my pressure was fine so far. A bit worried as I'm 42, on aspirin which should prevent things like that. I'm generally fit and healthy, not overweight, but my bump is really big and weights on me. Anyone had similar experience and how did it go?
