Where is AF?!?!

Meagan

I got a flashing smiley face on my ClearBlue OPK almost 20 days ago... (I also had EWCM which I usually get right around ovulation time.) So I assume that I ovulated around that time. But after ovulation, I always get symptoms leading up to AF. (Sore boobs, break outs, moody as hell, etc.) I haven't had any of those symptoms at all...AF was due 5 days ago and still hasn't shown up yet. There are still no signs that she is coming either. I tested this morning and got a BFN. This is really weird for me because my period has always been on time... have any of you experienced a similar situation? Advice? Thanks ladies!

Side note: I have experienced a little bit of heartburn, nausea, and creamy CM over the past couple of weeks which made me think I could possibly be pregnant. However, the BFN I got this morning just left me confused.

Update: AF is 6 days late. I took a test this morning. Vfl or bfn??
