Questionable still...

I know it's still early but I downloaded this app for help and just in case...I have a 23 day cycle... I am 6 days late... having lots of symptoms... but I can't seem to get that ppt.... I have taken lots now...lol .. all come out negative... not sure y... my doctor tells me with such a short cycle, I could have ovulated late, and it may still be too early which is why I'm not getting that +... told me to just wait it out.... any other moms out there have this happen...

I am a mom of 2... so this is not my first rodeo...???
