7 days late

So I just had my baby girl 5 months ago and it took a lot for me to conceive her she’s my second child and my son who’s the oldest is 8. I felt like I couldn’t have any kids and I’ve been blessed with 2 the thing is I haven’t started my period yet and I have a lot going on I don’t know if I should pin my missed cycle on stress and am I pregnant 🥺🤷🏽‍♀️🤦🏽‍♀️🙇🏽‍♀️ What should I do 🤔🤔🤔
