At first, I was amused because the ovum going "Egg!" reminds me of Sesame Street clips of Grover going, "Near!... Far!" Like they're both just so happy to be exclaiming monosyllabic words.
Then, when the drops came, the voice in my head went, "But... the ovum is no longer around by the onset of menstruation! Misinformation! Uterine blasphemy!" You can tell that I might have lived in VP for too long.
Then the end came, complete with endometrial avalanche. Not gonna lie, I'm glad periods are as catastrophic for someone else as they are for me -- even if that "someone else" is an inaccurately timed, animated talking ovum. I'll take what I can get.
And that is my late night critical analysis of a menstruation animation. :P
