I woke up this morning at 2:30am needing to go to the bathroom so I situp and I get this sharp stabbing pain in my left side I can't move or get up to go to the bathroom so I wait it out and finally it goes away after going to the bathroom I lay back down on my left side and it sorta comes back but it feels like a light cramp now so I think its just a braxton hick so I try and go back to sleep I rest for a good maybe two hours not fully being able to fall asleep when it comes back and worse this time where I'm in tears so I lay on my right side to try and calm the pain and it moves down like I'm having a horrible contraction along with the horrible cramp in my left side I can't stand it I can't barely move and if I do it gets even worse I'm trying not to scream and cry but then all of a sudden at 5:00 am the pain in my side just goes away the contraction ones are still there but the side pain went away then a min later the contractions stop so I go to the bathroom again and take my boyfriend to work and I get a contraction again when I got him there it went away while I was driving home and the light side pain started again and so I laid down and then it got worse like a cramp before a period or after you run too much but its worse its going away a bit now but I have no idea what it is..... should I be worried? anybody experience this? what is it?
