I have this same thing as we speak and I'm also 14DPO and I thought I was just having an IBS flare up. Even though, this is more than a month ago, I'm still really glad I stumbled upon your question. Now I know it could be something more!

diarrhoea and cold symptoms are sometimes associated with early pregnancy.
Hon, really won't know until you test again. maybe tomorrow?
