7 months of trying to conceive... frustrated. Advice?

So my boyfriend and I have been trying to conceive since march. We have sex at least once a day, even when I'm on my period. I was on the depo shot last year but Ive been off of it since march. Do any of you ladies have experience with depo and how long it took to conceive after the last shot? My boyfriend is very optimistic about it but I'm starting to worry. Please help and let me know if there is anything I could do to increase our chances. I just bought ovulation tests and pregnancy tests. I do need advice on when to do the ovulation tests though. Also, does anyone know if the K•Y• couples lube effects chances of conceiving? My boyfriend and I have been using that sometimes. Thank you guys so much in advance!❤️❤️❤️ In the photo you can tell I'm definitely not pregnant yet...
