Hello,
Welcome to HCM & Thanks for asking your question. Be assured that you will be satisfied with the answer.
Coming to your question, you have made a mistake by picking 27 pound at 32 weeks of
pregnancy. You must not bear heavy weight. Sometimes
abdominal pain occurs after doing walking or heavy work or like that and most of the times it runs away after taking sufficient rest for few hours.
According to your information, i don't think that it is
labor pain or something like that, so be relax and don't get stressed. If i were your doctor, i would prescribe you
isoxsuprine tablet. But it is a prescribed drug, you can better go to your gynec and get examined yourself.
I want to know whether pain is associated with any kind of discharge from vagina or not, watery or blood.
I would suggest you to take sufficient rest and get yourself examined by gynec. Hope this will help you and best of luck for your pregnancy.
