Bby fever anxiety? Lol

I’m a first time mom. I’ve been dealing with a guy for some time now & we just randomly had a conversation about kids & he told me somewhere down the time he would love to have a child with me. Then jokes about it saying only because of my good genetics lol

Well ever since than I can’t help but to feel horrible about ever having another child in general. With my first I experienced a horrible labor. During my whole pregnancy I worked from home, no friends , just enjoyed my pregnancy alone + work. My child father wasn’t there still isn’t. That was a bit depressing at first I gotten over it 4months in . But long story short after given birth to my bby a doctor comes into my room telling me social services was coming in afterwards because they found Ecstasy in my pee. Well that completely disturbed me because I know this was false that they might’ve gotten mine completely mixed up with someone else’s.. well my child was fine had to give pee blood was fine everything was fine yet I was still being accused of this horrible assumption. It just bothers me about ever having another child. Because doctors can make huge mistakes effecting others lives. I think I’m still a bit freighted by my first time experience & I believe it’s holding me back from ever wanting anymore.. [ I don’t want anymore but who knows I could meet Prince Charming lol ] i was so heartbroken confused just in shocked that it happened to me when I know I’ve done everything right while pregnant.. just scared it’s always on my mind randomly
