TTC...I may have already... not sure 🤔 Advice??

Victoria
This is my first rodeo I'm 31 TTC so if there is any moms out there who has some knowledge please feel free to share. So the last time AF visited was on June 12th-17th 6 days and on day 6 AF just left, didn't hang around just went clear.... my period is usually 7-8 days Solid. Also 14 days before AF Iightly spotted for 3days......I don't think I'm pregnant just a little confused, I would be over joyed and beyond ecstatic if I was!! This was just weird....has this happen to any of you? Or can someone maybe explain as to why this may have occurred. Â
