Should I test?

chey 🐝🌻 • Mommy to be 10/24/22 🤰🏼; Pregnant with PCOS. ✨
I took a pregnancy test March 4th,  which was BFN.( I took the test the day after my period just to be extra sure) I TTCed March 12th. I had spotting 3 days later for a day or two. My last period was 2/27/16. I also TTCed March 25th, 26th and April 2nd. 
So is it possible that I might be pregnant? I have pcos also so irregular periods most of the time.
