Is this just a really bad cold?

I'm going really hot then really cold, my nose is all stuffy and coughing like mad so I was like right I've got a cold, went docs they said lemon, honey and water is only thing I can take... Come back had a nap and had 2 baths and now I'm in bed and my tummy keeps going abit tight with cramps now and again and it's stopping me from napping I'm 19 weeks tomorrow :( I've never been this poorly and sore before
