I'm having stomach flu for the last 3 weeks, and I've been drinking 3 kinds of of medicine until now. My last period starts on 6 of Nov, and a wek after i started to vomit a lot in and feel nauseated. When i ask the doctor he told that I have stomach virus, coz there is nothing wrong with my blood test and everything is normal. Last 25th of Nov I got my period but it started as brownish type and then stop the very next day. I'm just worried how can that happen, would be because i'm taking medication and I'm so ill for the last 3 weeks? Please someone advice.
