Obsessing over ttc # 2

Am I the only one who's obsessing? We had a quick and easy conception with our amazing son, who is my little love💖. Now, I feel crazed while ttc a second child. I'm 38 and my son is almost 5 mos. The first time we weren't really trying and now we 'unofficially are'. This is way more stressful this time around. I try to remain the relaxed mom people see but I'm secretly taking pregnancy tests just hoping and still bfn. Uph. I'm so grateful I even have one child so I don't know why I feel this necessity all of the sudden. I need to just chill out!! Had to vent for a second.
