it happened!! I totally thought I was out this month

Of course I thought I was out this month, I've been drinking and I'm currently on vacation. I have a ton of tests at home, but I didn't bring any on my trip and I'm two days late. I thought I was out because my basal body temp was way down and I had period symptoms. I even had implantation bleeding Friday and used a tampon... but nothing further came of it. I feel so blessed and scared that it could go away at any minute. Scared that drinking and being in 100 degree heat all weekend could have poor effects on the baby.Baby dust to everyone still trying and thank you for the baby dust given!
