Just take a test. I do this when things feel off or my period is one minute late.
And, the way you felt last time might not apply with a second pregnancy.
I know. I was going to stop on my way home today, but came home to nap instead. hahaah.
If you are not normally a napper, I would definitely test. I can't even remember what pinged my radar (other than having no PMS symptoms at all and my period was due), but every time I tested positive I just had a feeling.
