help...

can one of you ladies help me? i am currently 4w6d so super super early i'm still getting crampy like my period is about to come but cramps aren't as bad as usual... anyways this morning i was half asleep and i was getting one of my "lightning crotch" cramps.. i also needed to let out some gas.. so i pushed to do so and gave myself a sharp pain in my right upper corner of my uterus... it's gone away now but still is a little tender.. is this a cause for concern??
