Giving up

Hailey • 18. trying for baby #1...
I got off Depo December 2015... And I've been ttc for 5 months. Right after I got off Depo my periods went back to normal. Last month I took an ovulation test and had an lh surge so I've been having sex on my fertile and ovulation days. And then aunt flow came.... Now just hoping that this month it sticks. Any opinions ??
