For the whole week I have feeling pain in the lower part of my belly, to me it feels like mild contractions. This is my third pregnancy and I did not experience anything like it with my other two kids. The pain only feels worse when I'm sitting down, the baby gets very active and it feels like he is pushing down. I'm Almost 31 weeks. Has anyone experienced something like it or is someone else feeling the same thing? Thank you in advance for any help.
