Should I take a pregnancy test?!

The past 3 days I've felt like I was going to throw up mostly in the morning. Well today I did throw up I seem to be really tired. The other day I noticed just one spot of clear "fluid" kinda coming from one of my nipples it's a pen size spot. I start my period in 4 days. My partner and I have been trying but just started this month. Should I take a test or just wait for my period?!
