Help! Help! Help!

I am desperate for advice. I have had this same cold for 7 friggin weeks. Docs think it's a sinus infection and gave me antibiotics but obviously it's not safe to use them. So I have them if I get any worse but right now I'm trying natural remedies. So far I'm on the salen salt water spray. But I Want to try the netipot is that ok to use while pregnant and which one? If anyone has any other remedies please tell me. I feel like I haven't slept in 7 weeks and I would so cry from frustration but that won't help my congestion. Please help me!
