hi

yesterday I was doing some painting work outside and I felt some sharp pain on the right side of the belly button. the pain was stringer when I walk and when I straighten my back it was a really sharp pain but just on that one side. I lie down to take some rest and I haven't feel pain I just felt it when I press that area but after 1 hour of resting I get up the pain was still there. the pain lasted for 4 hours. today I'm feeling OK. I tried to phone my midwife yesterday but nobody was picking the phone. I feel baby movement so I wasn't really that paranoid but still I want to make sure that everything is OK. is any of you had something like that? please let me know. many thanks
