Is there anything I can do to help with allergies while pregnant?

I am 7 wks pregnant and have very bad allergies. I usually take a nasal spray that they took me off of when we found out I was pregnant. For the past week it has been awful! My eyes are red and itchy, my throat has drainage and itches, my nose runs out of control. I dont want to do anything to harm the baby, so if I have to deal with it I will gladly do so, but has anyone found anything safe that will help me get some sort of releif or at least a nights sleep with out having to wake up and blow my nose every 15 mins.
