Hi,

Here's some thoughts...

You may have 'O'd earlier in your cycle this time and caught the egg? (Are your cycles regular 32 days?)
Usually just before my period I have less appetite but if pg I eat a lot more.
Pregnancies are all so different, so sore bb's could be a symptom this time.
I would test, just to be sure with an early test.

All the best either way xoxo
