I had my IUD removed in January. Since then I have been tracking my period. Last 2 months it was 2 days shorter than usual. I also take ovulation tests since I'm trying to conceive. The day it said I was ovulating, I noticed I was spotting. Next day nothing,  the following day another spotting. This carried on for 6 days same pattern. I am due for my period on the 1st of June, but the last 2 days I been nauseous and very emotional. Is it too soon to take a pregnancy test?!? Should I be worried about something else?!?
