Hi hun,

I hope you're UTD!! I was going through something similar to you lately, where I was 4 days late (and like you I'm never late!) and I got 3 BFNs in the last few days, wondering if I was pg. Doc told me to wait a week before having a BT but AF arrived today Apparently, sometimes the HCG levels are too low to detect on even the most sensitive HPTs.
My friend at work told me today that she was a week late when she got pg last year, and the HPTs all showed BFN, and then the BT confirmed a positive a week later.

So there is still a great chance for you hun!!

Good luck sweets!
