Hi, I am new here but have been reading and wanted to ask a question myself and get OP. My period should have started today according to mymonthlycycles but it has not. I noticed my breast were tender a couple of days ago; mainly my left which is now a little bigger than my right one. I have tried to keep track of my CP but am still new at it. Yesterday morning it was low and seemed a little soft and I had watery yellowish CM. This morning I can not feel it as it must be to high to check, but it seemed yesterday to be pointing more up. I took an HPT 2 days ago but it was negative. I dont have any other symptoms of being pregnant other than I have gained a few pounds. The sore breast are what caught my attention as I never get that before my AF. The last time I remember getting sore breast was 10 yrs ago when I was on the patch BC. Also, I do not know exactly my ovulation date but according to the site it should have been around the 18th of May and my last period was May 3 which lasted about 6-7 days. Any advice would be great!
