I'm so confused! My son has a bad stomach bug... vomiting and diarrhea violently. I was sick today with nausea and a low grade fever/lack of hunger. I thought I caught what he had until my husband got sick tonight. He is vomiting/ diarrhea  violently as well. I was having regular Braxton hicks the past few days and today the baby feels really low and I'm scared it's actually prelabor symptoms! Anyone have flu symptoms before labor? How long before?
