Whats the best way to treat a head cold when pregnant?

Hina

Im 22 weeks and I have been fortunate so far to have not been ill (apart from nausea and vomiting but that doesnt count!). I cant really afford to be ill right now as I have a family wedding to attend this week! I want to get better as quickly as I can. Im afraid attending this wedding will make me feel worse but i really cant miss it as its family.

I just want to know what has worked for others. Thank you.
