How dare this guy judge you for taking control of your own reproductive health? I dislike him already.
I hope you took some Emergency Contraception. Also, I honestly won't judge you for staying silent about this until you can test. If this asshole boyfriend of yours freaks out on you just for taking some herbs, then, in my mind, he's forfeited the right to know what's going on with you during this two week wait to test.
If you're pregnant, of course you'll tell him. But why re-open a stupid argument about what you have the right to do with your own body? Of course you have the right to take the EC pill and herbs, and his opinion about that doesn't matter. Just do it.
I know I've offered a slightly different perspective than the general opinion, here, but I'm genuinely peeved about this guy's unacceptable behaviour.
