Thanks ladies, im starting to get cramps so im on my way.
I would go to the ER as well. Everything is likely fine, but I would personally just want to put my fears at ease. The extra worry might stress you out and you don't need extra stress!! Good luck!
Better to be safe I would go to the ER. Even if its just for your piece of mind :)
Its always better to be safe then sorry :) especially when there's suck a small baby involved!!
