Possible Chemical Pregnancy?

Brooke • 24, living life with my main squeeze and our fur kids.

So I track my cycles on here and Fertility Friend. Glow said I was fertile between cd15-19. Though I was in the clear. Norm cycle runs 30-34days. Had unprotected sex on cd22. Fertility Friend then decides to say I ovulated on cd24!! Which means according to it I was fertile on cd22. Currently 11dpo according to FF and on cd34. I have felt my normal PMS symptoms since cd32....achy cramps, sore breasts, was bloated a few days before but no AF yet, but feel like she can come anytime. Took a Walmart brand hpt today @ 11dpo and it was + ( faint, but still + ). In the past I had noticed my luteal phases were short (9-11 days). Part of me wonders if we conceived but it didn't take since it was so faint and I feel like I'm about to start AF.

Any thoughts?
