5 days late...

I. Am. Freaking. Out. My husband and I have a 14 month old and he's still nursing so I haven't gone back on birth control so we've been using condoms but occasionally use the pull out method. And now here we are 5 days late. I cannot have another baby right now. My husband loves our son, but he's not the best dad. He doesn't know how to bond with an infant or take care of them. I can't be pregnant. I can't. I track my period like clock work and it's never been more than a couple days late. Y'all. Please talk me out of the panic attack I'm about to have
