Flu/Cold Symptom before BFP. Does medicine not help?

Anonymous

So starting Sunday I woke up with a sore throat, nausea all day, and I vomited twice. The next day I was coughing running a fever dizziness cold, hot/cold flashes sinus infection stomach pain and no medication was helping. So few days later I went to the hospital I was still feeling the same but they said I had no fever. I asked for them to give me a blood pregnancy test since I haven't come on my period yet but they only gave me urine and said that they were both equally accurate which was very wrong. I left with a upper respiratory infection and kidney stone. Now I'm home I'm a little more mobile and the stone has passed but I still feel as if medicine is not really helping I still feel like crap just wondering if any of you ladies took flu meds for flu symptoms meds before for your bfp and it wasn't helping because you were pregnant?
