Irish twins

Okay so I need some mom talk here, my son is 3.5months old (our first) and is ebf. I know it’s not “100%” birth control but I literally can’t take birthcontrol because it makes me turn into a crazy person.

It took us 2.5 years to conceive him, actively trying each month

ANYWAYS

I’ve been having the craziest dreams, so vivid and have been nauseous everytime I eat for the last few days.

I am not “afraid” I’m pregnant just curious how many moms have Irish twins and how you knew to take a test with no period (still haven’t had one since giving birth)
