Sudafed while pregnant?

Jessica

I’m 5 weeks today. I’ve been congested and last week my OB told my I could take Sudafed. I’ve been taking it for about 4 days, and one of the articles on my other <a href="https://play.google.com/store/apps/details?id=com.glow.android.nurture">pregnancy app</a> was about the medicines you can and cannot take while pregnant. Sudafed was on the “do not take” list. So....have you taken this while pregnant? I know I should listen to my doctor but now I’m nervous!
