I'm 15.5 weeks, does that make me 3 months pregnant?

Everyone is asking me how far along I am. I am telling everyone I'm 3 months along (and will be 4 months in a few days; my husband corrected me and told me "no, you're in your fourth month and in a few days will be entering your 5th month once you get to 16 weeks" Who is right??  I'm 15 weeks, 5 days.
