I'm about 22dpo. AF is 8 days late today and there is absolutely NO sign of her (no spotting, no cramps, headaches or mood swings). But I've been getting all BFN on dollar store tests.

According to my calendar, I should be starting to use my OPK next Monday...

Should I even bother and save them until after AF shows? I don't want to waste them, but I also don't want to waste a cycle.

Should I use a more expensive digital test? Or just skip right to a blood test? Ugh, I'm so confused.
