6 Days Late - Negative Pregnancy Tests

Amy

I am 6 days late and have taken 2 pregnancy tests that are both negative. I have never been this late before and I’ve experienced some symptoms like nausea, headache, stomach cramps, and hot flashes at nighttime. I don’t think I am pregnant because of the negative tests but after 2 years TTC, this seems like a mean trick. Any one else experience this before? So many strange signals...
