Hoping to be in the 2WW

So we weren't going to start trying again until June..but we went away for the weekend and he didn't pull out Saturday or yesterday..glow has today as my most fertile day...so even though we weren't really trying I'm really hoping this will be it..I know I'll be disappointed if my period shows up on the 16th ..also I had a miscarriage in sept and another in December I've given myself some time since the last one and I've stayed on my prenatals so I feel like I've done all I can but I'm still nervous..so what do y'all think do I have a good shot..
