Help!!! Question re early period

So my period was due on 3-4 May. It came on 1st May and was heavy with large clots but only lasted 2 days. Very unusual for me. Today I wiped and had a link discharge only once this morning. I have done tests on Monday and Wed but all BFN so requested a blood test. Glow is telling me I am ovulating now and am on cycle day 9 I think will need to check. What are your thoughts ladies? I doubt I am pregnant but could it be possible?
