Could I be pregnant or is it just me

Emma

Hey ladies so my periods are always on time every month 4 days on and every 28 days. My last full 4 day period was 29th March. I was suppose to start my period 9 days ago. I had 2 days where I had very light bleeding almost brown and no cramping now nothing normally AF is always on time every month. Been feeling very nausea and very unwell for a few days now. Just wondering do you think I should do a pregnancy test as so want to be pregnant but scared I'm going to get another negative been trying for 1 year now and still nothing. Xxx
