This month is almost over...

I<3Dolphins • I`m a 23 year old Military wife. My husband and I have been TTC #1 since November 13, 2013. ✨
And I still haven't had my period. I'm a week and two days late (according to Glow). I took a test 2 days before I was supposed to start and it was a BFN. I took another one two or three days ago and it was also a BFN. 
​What should I do?
