My friend recently found out she was pregnant @ 30 weeks. The reason she didn't know was last year she'd had an injury which caused AF to stop. It had returned and then stopped again so she thought nothing of it. She got a bit sick but just thought it was due to being a school teacher and working around kids who had the flu and passed it on. She finally went to her Dr saying she was worried that AF hadn't returned and they tested her and she was pg. They did an u/s and the baby was facing toward her back and kicking in that direction she said she had felt something but thought it was just wind moving through her bowels or something, but now it all added up for her. I couldn't believe it, so she'll be giving birth 5 weeks after me and she was only saying about 3 months ago how she was planning on waiting another few years before having kids, ooops!
