Surprise pregnancy!

So I’m freaking out...I’ve just had a baby in June so he’s 7 months now. My periods have been all over the place and I didn’t have one for 6 weeks so to put my mind at ease I did a test this morning and it was positive!!!!!!!! This means I’m going to have a 15 month old and a new born....Has anyone else been in this situation?? I’m really scared about it all 😱
