Please help me!! ppl

Okay, I was pretty scared to make a post, but I need help!!

I had my last cycle June 8-12... (Keep in mind, we are ttc)..... Glo told me to make sure I had sex 6/22 (which I did...and probably everyday after that)

My next cycle was supposed to be here July 3-8, but she's still not here! :-)

I've been having the worst lower backs in the world
