Hi all. Im 28 weeks tomorrow and for the past few days I have been getting an increase in what feels like I would right before my period. Like a very heavy feeling "down there" and in the low stomach. Sometimes into my thighs. I also noticed about a week or two ago that LO isnt as active as normal but when i called the dr they said as long as you feel her sometime during the day that they dont start counting kicks til 28 weeks. I also get like sharp sudden pains my the very edge of my back into my side along with the feeling like im going to get my period any second. I don't want to keep calling dr and seem like im crazy I just have no idea what any of it is as this is my first pregnancy. I am 18 and due Aug 25... Any advice?
