BFP?! anyone else?!

So I was having symptoms and sure enough got my BFP today. I have no idea due date since I'm breast feeding and haven't had my period return yet and haven't taken any pregnancy tests post partum. I know... I seem stupid. 2nd kid and didn't have any issues my first time around so I just assumed I'd be fine this time with our same preventative methods. Still processing because hubby and I never actually agreed 100% on having 3 kids. It was still just talk at this stage. 🙈
