Had a frozen embryo transfer almost three weeks ago, beta was negative at 2 weeks post, but now AF has not appeared. I'm anxious to get back in the saddle and TTC naturally, but i can't tell if anything has restarted for me. I never have a period the first cycle after coming off BCP either, but I know that things start back up with it, because I've conceived twice that way, so I'm hoping that's what's going on. Curious to hear others' experiences. Thanks!
