Clear Blue VS OPK Strip - am I the only one?!

Sarah • 34 y/o. Baby boy born Jan 15, 2020. Pregnant with # 2. Stepmom to a 14 year old.

(See pics below)

1) Am I the only one who gets obvious LH peak on OPK, but zilch zero bupkis on Clear Blue Digital? I've used a few different strips for my CBD (not expired), yet it doesn't pick it up! Is it just me? My OPKs are obviously peaking! Had EWCM yesterday, lube/wet today, CM high/soft.

2) Also, anyone get strange srsly LOW temps in the middle of the night, accompanied by bad cold sweats?! I woke at 330am with night sweats, managed to take my BBT before moving, and here are the (shocking??) results! Temps taking back to back (at 3:30am):

93.41 (what??!! 93 effin' degrees?!)

94.46 (huh?!!)

97.91(okay, that's better..?)

*and remember, I woke up cold, but my bed/body DRENCHED in sweat!

Note: also brand new batteries in my thermometer. For charting sake, I used my last temp as the final one for today's log.

3) This is officially 1st mo TTC, using FAM charting and OPKs. How many more days should we BD after peak (today)? Sorry if that's a lame question! #newbie

Thanks for all the help! Baby dust!
