I have been careful for weeks not to catch anything. And staying away from people. But cant avoid when people bring friends home sick!

Last three days i had throat pain now, its now runny blocked nose.

Im so scared that this cold or flu will drain me. Im 16 weeks pregnant. I was severe ill at 8 weeks and was put in hospital.

Can i take anything to prevent this?

Like strepsil for thorat. Something for the blocked stuffy nose?

Thanks for your advice ladies xx
