Needless to say this is driving me crazy! I'm now on my 4th day of no AF, I have taken 3 HPTs and all BFN :( I've had cramps off an on for the past 4-5 days and have had really sore boobs. Today I've been dizzy and have a horrible headache out of no where. I haven't been logging my BBT but my husband hasn't been able to sleep with me for the past week because he says "I'm like an oven" and my body temperature is too hot. I've heard of late BFP's but seriously doubting it at this point....
