Only 7 weeks and nausea is killing me

What can I do?? I've tried ginger, pressure, lemon, peppermint.. It's 830am and I've be dry retching since 5 almost non stop: I've already had 3 days of work off in the last two weeks. I don't want this to affect my job as I'm a manager in local government and is so busy this time of year but I just can't do anything without feeling like I'm going to spew everywhere and faint. Help!!
