Sinus pressure and cough

Nickie • 28 years old with 3 children ages 6, 3, and newborn!
I'm 4 weeks amd 3 days according to Glow and I feel so gross! Sinus pressure, coughing, and sneezing. I would usually take Sudafed PE but I've read scary stuff about that during the first trimester. I use Neti pot and steam but I'm curious to know if anyone had other suggestions. Help!
