Trying not to obssess over getting pregnant

My last pregnancy. I planned and had sex on certain days of my fertile cycle. Tracked every symptom on Glow. Basically wanted it so bad. and Bam! got my Bfp! Noowwwww... My SO wants to have another baby. Him more then I, but I find myself getting overly excited and wanting to fall back into what I did before. I just don't want to be like that and it's pretty hard to hold back. 😥 I just want it to be a surprise, like just find out the day I realize I missed my period etc. Basically I don't want to turn crazy over this!
