Still a bit confused and worried. (Poss tmi no pic)

So, I'm on my first proper cycle after having my nexplanon removed. But because I have no idea of my cycle pattern, I'm pretty much OPKing everyday, so I don't miss my peak time. Up until yesterday, my OPKs only showed one line, now I have a faint second. I know the line has to be the same colour as the test line to be positive, but I had a very small rise in BBT this morning and I have EWCM. Soooo....don't know if I should trust my body or the OPKs. 
DH is away most of this weekend and I'm terrified we are going to miss our window.
