Weird question here.. Im pregnant with my second and I am noticing a bluish/purple line on my 🍑. I’ve seen and heard ppl talk about that being an indicator or dilation.. I’ve been having period like cramps off and on for a little over a week, a lot of pressure down there and just today I’m at that point where no position is comfortable for me… what do you other mommas think I should do?
