Weird !

So yesterday me nd my man had sex after 2weeks not having done anything .. It was amazinggggg ;) lol ..ANYWAY .. As I was getting up to clean myself up ..I started having really intense sharp pains in my belly ..all I could compare them to were the pains I was getting while I was missacarrying.. Yesterday they lasted for a good 20 mins .. Untill I had the feeling I wanted to throw up I ran to the bathroom ..puked and then like 10mins later the pains completely went away ... Any ideas on what that was all about ladies? .. My period ended a little over a week ago .. Never ever have I had pains like that after sex
