hi there, I'm in my 16th weeks and I also have increased cramps occurring on my right side of the abdominal area. I went to KKH urgent OB centre to check it out to be sure that everything was normal and thankful it is. I will suggest you get it check out and rule out any risk. doctors I met shared that my abdominal cramps can be caused by baby development, movement and also bcos I have got a cold and have been coughing badly which used alot of my tummy muscles. hope all is well for you!!
