Period

My AF was due yesterday & still has yet to arrive. There's a chance I could be pregnant, as we don't use protection (other than the pullout method). I wouldn't be disappointed if I was pregnant, honestly. But I don't think I am. I've been under so much stress lately, from watching a close family friend have a seizure, to having to go to the doctors, to finding out I need more tests done to find out what's wrong with me.. it's been a crazy 2 weeks. I guess my question is, is there anyway to get it going if it is going to come? I just wanna get it over with.
