OPK Confusion

I got a smiley on a clear blue digital but the opk says low. Second cycle TTC, had no peak last month and always have had no second line except for close to ovulation. I got pregnant my second cycle last time and wasn’t closely tracking so not sure I ever got a “peak” and can’t remember if I even tested first cycle. I’ll keep testing, but if it never goes fully as dark is this likely a peak for me? Also when is the temp expected to peak after a positive opk?

PS-both tests below are the same strip?
