BFN and no period!

Amanda

Hey ladies! AF is 9 days late. I took two First Response tests 4 days after my missed period, one at night and one in morning, but both came back negative. I took another today, cheapo kind from dollar store, and it was negative. My breasts are sore, my lower back is achy, and I have light cramping. I can barely get comfortable to sleep at night and it's starting to get to me that I'm getting BFN time after time. Anyone have the same symptoms? HELP! TIA!

GOOD LUCK TO EVERYONE TTC!
