2 under 2 and mixed emotions

I just found out I am pregnant with my 2nd! My first will be 1 in 2 weeks and I’m mildly panicking. We were going to wait a little longer and with having pcos and needing help with fertility meds the first time around, I honestly thought there would be minimal risk having unprotected sex bc I rarely ovulate. I was wrong! Thrilled it happened on our own but also scared of how challenging it will be having our babies so close together. Positive vibes please!
