I Regret trying for a baby...

I’m kind of freaking out. I have two daughters, a 7 year old and 2 year old. My 2nd pregnancy was REALLY REALLY hard. I had the worst depression(like suicidal), I was sooooooo sick throughout, and just a bunch of other problems. My first pregnancy was perfect and amazing. After my 2nd was born, my depression instantly went away and I felt great. Everything has been going fine up until this corona virus hit and this semester of college has been really hard and stressful. My husband has a wonderful paying job and we have a great home, we decided last year that we would start trying for our third baby around this time. This week is my fertile window and my husband has came inside me twice and I honestly regret it. I know for a fact I want more children but to be honest now that i could be pregnant, I don’t think I am mentally ready yet with everything going on. My anxiety and depression has suddenly felt like it’s creeping on me and I really think it’s because I had such a hard pregnancy last time, I am absolutely so scared I’m going to have another hard one. It’s like I was traumatized from my last pregnancy and now I’m legit about to have a panic attack at the thought of having a pregnancy like that again. I guess I’m just looking for some encouragement. It took us 6 months to get pregnant last time so I really hope I’m not pregnant this easy 😓😰
