I Have A Sore Throat With Blisters On My Throat Why Sores On Tongue. Especially On The Tip.?

Sores on tongue. especially on the tip.? - i have a sore throat with blisters on my throat why

I do not know what's going on I am 14 weeks pregnant. A week ago I started to notice that my tongue was painful, especially the tip. I had burned a sore throat for three days, and my tongue. It hurts bad today, my husband looked at my tongue the night for me and he told me that this is not the form of blisters or sores (4 each side) of the tongue tip. I do not know what to do. Are cancer sores? Ive never had a cancer sore. Why is my language? Should I call a doctor or wait until my appointment with my midwife in a week? whats wrong with me?
