12 weeks.. No end to morning sickness!

12 weeks today was really hope my morning sickness (even though it hasn't been awful) would completely go away around this time but I spent about 3 hours I the ER today for vomiting with blood streaks in it. I've avoided medication as much as I can (I'm what you call a crunchy momma to be) trying to handle everything as naturally as I can with high blood pressure being the exception, but I can't handle puking blood again. So zofran for me it is! Anyone else hoping morning sickness is almost done with you?
