I lied to my teacher about having missed a lecture because of periods. I know it's playing the girl card, but only because she wasn't accepting any other excuses. If you've been to a wedding, show the wedding invitation card. If you had an appointment with the doctor, bring the prescription and a medical certificate. If you were on bedrest, who asked you to be on bedrest? Never lie. 0 marks is okay, but playing the woman card isn't. It's a patriarchal world, true. But you have to be fair only to yourself and to no one else. Don't let yourself down with respect to your morals. Remember, not this time, but if you continue to do so then it might come back to you. A girl might take periods when you need her to be present, for her benefit only.

Stay in the present only, don't think of the future or the past, but do no wrong.
