17 days pp! Baby blues?

Jayda • 20 years old, married, first pregnancy & expecting April 2nd❤️

I had a traumatic birth experience due to preeclampsia. Baby was born at 35 weeks and my husband is away in the military. I fight anxiety and depression. Well 3 days after we got home, I started to become very sad. I cry a lot, my anxiety has been bad. I don’t think it’s PPA because my anxiety isn’t about the baby, I think it’s just cause I’m overly stressed. I started my lexapro 3 weeks ago because I was on it before I got pregnant and still no improvements. I know ssris can take awhile. I’m still adjusting to the no sleep. I love my baby so much. I have only been feeling like this for 12 days. Is this baby blues??
