I'm 16 weeks with my second child and I've started to experience lower pelvic pain that comes and goes, it's not a sharp pain but a dull pain ( kind of like the ones you get during the 3rd trimester if you've had a baby before) I'm not too worried since I remember these with my frist pregnancy and am wondering if it's because my this is my second pregnancy and my body is just more relaxed?  Have any of you  second time moms started having lower pelvic pain?
