first time trying!!!

I guess hubby and I were in the Christmas spirit. We Talked about "trying" in 2017. I've been birth control free for three years and we've been using condoms. Once we got married we started "pulling out" which I realize isn't so much a method as "fingers crossed" lol but we went for it, no pulling out yesterday morning and now I'm totally bugging out. I swear my stomach feels funny, almost like faint cramps. I start ovulating tomorrow. Am I being crazy???
