Josephine
38+3 days and I can't quiet put my finger on it. All I know is I'm having a constant pain in my lower abdomen/pelvic area... it's not contractions or BH because those come in waves I got up and walked around besides feeling crotch lightening I didn't feel anything else... All I know is I'm extremely uncomfortable just want to lay down and I don't remember experiencing this will my first. Whaaaaat is this?
