i got this staring today and it was really watery. It was light pink discharge when i wiped and was a darker pink in my underwear. I have been trying to conceive but still a bit confused on how to tell if its AF coming, or if its implantation bleeding. ive been having very faint cramps for the last two weeks on an off, and about a week ago and half or so ago i was getting hot flashes on and off for 3 days straight 3 times a day, then it went away. Can you help me??
