i have pcos, very irregular periods and am on my 2nd cycle of clomid. last month i ovulated, but got BFN, this month i didnt chart or use opk's i just looked for EWCM, but we only BD once! normally we BD alot more... im now 18 dpo (last cycle AF came at 17dpo) i think and the past 3 days my boobs have KILLED. ive never had boob pain before, they feel bruised inside, and when i take my bra off they really hurt! since last night ive had mild cramps so i think AF is en route, but im being really good not testing. ive ordered some HPT's online but they arent going to come till Tues or Weds. i dont know if i should go and buy some and put my self out my misery, or just hang on till mid week, and either AF will be here or i will test! i just cant face the disapointment of BFN again.
