Help. What to use. And support. 😔

Weve been trying for over 4 months.. and to no avail.. what opks and cheap pregnancy tests do you use? The strips preferably. I've spend wayy too much on FRER at this point. Any tips and tricks on how to track ovulation other than cm and the 7 apps I have on my phone? I'm at a loss. Af in 4 days and it's looking like I'm out. Still negatives. Getting discouraged. Anyone want to be a cycle buddy, or ttc friend? Other than my spouse, I'm alone on this journey.
