Hi A.,
Sorry to hear you're still feeling under the weather. If you're feeling that you need to go to the hospital, then don't wait until your next appointment. Our body's are remarkable when we have faith in their ability to heal themselves.
Rest, extra fluids (soaking in a bath tub can help), extra vitamin C (too much will give you loose stools), probiotics (live active culture yogurts are a good source of this but one without added sugars, ie high fructose corn syrup, amino sweet, aspartame, sucralose, etc), Grapefruit Seed Extract, aka GSE(If you have a natural health store near you they should carry this.
http://www.luckyvitamin.com/p-2948-nutribiotic-gse-grapef..., eliminate any added sugars from your diet...sugar weakens our immune system and feeds the virus/bacteria. Were you able to look into a chiroprator in your area?
If you do go to the hospital and find you have strep, they will give you antibiotics to treat this. You'll want to take probiotics daily, watch your diet and GSE is helpful for yeast. Being pregnant you'll want to watch for any signs of yeast infection. This is important because if you're planning to breastfeed, your baby could get the yeast infection and this is called thrush. You and your baby would both need to be treated.
Feel better soon.
Peace,
J.
