About 3 weeks back, I have been getting contractions which are not so painful and not so close together so I know not to really worry about it because they are the Braxton Hick's Contractions. But a few days ago I have been feeling a sharp pain on my lower right side of my abdomen more like where I have gotten my C-Section done in 2008 after I had my first child. This is my second child and it scares me because following the pain I start to feel like pressure on my chest and find it hard to breath. I'm very concerned but I do not want to go to the hospital on false alarm. I want to know why I have been feeling this and what can I do to prevent it or what steps to take from here because I am very concerned and not only that, I'm actually scared because I still need 13 weeks before he should be born and I fear having a premature labor.
