Congrats mama, kahit surprise! Honestly a lot of us have been there, one of my mum friends got pregnant at 14 months PP din and was so stressed about telling her parents, pero surprise na lang, they were actually excited about the second baby coming (though nanay mo might have opinions, haha). The good news is your OB appointment bukas will give you peace of mind, so try to relax muna and see what they say about your health and how close the pregnancies are, kaya mo yan, and honestly after the initial shock, most families come around quickly once they see you're managing okay. Let us know how it goes sa OB, mama!
