Father's Day

My SO is planning something big for himself since I am due the day before the holiday, I can't help but get pissed off, jealous, and cry because he gets to celebrate it and I didn't get Mother's Day... As women we sacrifice everything just because we love our children too but we can't get spoiled because we haven't given birth? I feel like we deserve Mother's Day even if we're pregnant. Am I being selfish and over dramatic?
