Anxiety filled pregnancy vs medicated pregnancy

I have two boys who I love dearly and would love to have another. I have a history of anxiety and OCD since a little girl. Both pregnancies I had anxiety and OCD during and severe PPA and OCD afterwards. I suffered after my first for 18 months and couldn’t stomach suffering like that again so I got on medication 4-5 days postpartum after my second. 20mg Prozac changed my life. That was three years ago, I am now on 40mg Prozac and 15mg buspirone. I was just wondering if anyone has had a similar situation of a hard postpartum then experienced a pregnancy and postpartum while still on medication and if it went better? If you had a completely different experience than the first time and felt better while taking the medication? It breaks my heart to think I couldn’t have another, but obviously am concerned for my mental health and just want to be okay for my family and babies. (I have already talked with my mental health professionals I just want to hear from someone who has been through and is willing to share!)
