i am 18 weeks pregnant and have for the last 3 days had pains in my groin/ pelvic area on the right hand side off and on. It hurts for about 1//2 hour or so then goes off for most of the day to a dull ache it feels reallly bad and didnt know where to put myself it hurt that much. is this normal or am i being a big girly wuss? wondering if this is ligaments stretching ? advice needed. thanks
