ALLERGIES! HELP!!

My allergies are horrible right now, I have somewhat of a phlegmy cough and my sinuses are horrible. I'm waking up with sinus pressure and feel like I have a cold. Help!! What are some of the home remedies you other expecting moms do to help with allergies and sinus pressure. I'm drinking tea or water with lemon and honey for cough and heard pineapple juice works great for coughs as well. My daughter, she's almost four and has them just as bad as me also.
