is it bad to be jealous and selfish?

so my BFF tells me that she stopped taking birth control. which means at anytime soon she could get pregnant. she said that she isn't timing it or anything, but she isn't ignoring the timing either. i want her to be pregnant, but selfishly, not before me! is that bad? I so want to have my first before she has her second. I don't want her to have trouble, i just want to have mine first. i know it sounds bad, but its how i feel. Dear Lord, please let me have healthy children. Thank you Amen
