Anyone else get pregnant too soon after birth???

This is a total surprise... My contraception has failed me and I only gave birth 4 months ago..

I am now pregnant with my 4th who's due date is my 3rd child's first birthday!!!!

To say I'm worried is an understatement... Anyone else pregnant so soon and everything went well... I'm panicking myself so much that I just sit in tears

***apologies for posting anonymously... I have a lot of friends and family on this app and I've not yet told a soul I am pregnant again***
