Opk woes

[Dee1104]

Hey....newbie to the site but not new to TTC. We are currently TTC....while on a family vacation I might add....and of course, my body is giving me mixed signs. 3 days of "positive looking" OPKs....that has never happened to me. I used First Response OPKs this cycle when I usually use the amazon cheapies. Yesterday I had a 2.2° temp drop....today I had a 1° temp drop (was so hoping for a spike!!) I had CM a couple days ago but dont have any now. Any insight?
