Hi! I have been charting my temp for the last 4 months now,but this is the first cycle when i have noticed a triphasic curve from 10 DPO. I am usually quite dry after ovulation and get real bad sore boobs.But this month have been having CM more than usual and no sore boobs till now.Am due on 15th. Also,have been having abdominal pain since yesterday,like i am constipated (sorry dont get cramps or pain usually before AF so dont know whats that like.This describes it the best i think). Also have a funny taste,have brushed twice since morning Just to get rid of it. Any advice???????????
