About 5 weeks and sick with a cold

Jillian
Any Momma's or Momma's to be know of any tricks to help with severe congestion?? I took one Sudafed after I read it was safe but it didn't help much so I just took a Benadryl. Just being overly cautious. Anyone know if Zicam is safe? On the plus side, my Hcg jumped from 478 to 1140 in 48 hours! I'm scheduled for an ultrasound next week! 
Thanks in advance for the advice!
