k I'm 7DPO and a week away from my period. been feeling a lil nauseous lately, pulling on my left ovary mild cramps here n there on 5DPO till today they kinda faded away a bit. been peeing much much more than usual n I don't even drink anything all day. more importantly today before I got in the shower my both breast leaked colostrum. is that normal? could that be a good sign??? I have 2 children, 5 years ago and my other one 2 years ago. to which I didn't breastfeed either. my supply was really low with both. any one had this happen and get a BFP soon after? LEMME KNOW:)
