Am I pregnant or not??

Emily
How likely is it that I'm pregnant? This is what my month looks like... we didn't have sex at all during my fertile window but I'm not sure if I ovulated later than glow said. My period is now 3 days late and I took a pregnancy test yesterday and it was definitely negative but I didn't use fmu. This would be my first pregnancy so I'm just wondering what you guys think?? Thanks in advance.
