Hey there Ashley. At the outset, were you looking to get pregnant?
From your detailed history if accurate, you seem to have had great sex during your 'ovulation period' & assuming your cycles were hitherto regular & the awaited one is not here yet, yes..there is a chance you could be pregnant. It is not necessary however that the symptoms you exhibit could be those of pregnancy
only. They may just as easily be hunger pangs, gastritis
etc. Having said that, home pregnancy tests
are notoriously unreliable. So go across to a laboratory near you & do a serum/blood B-HCG
test that will be more accurate & give you a 'titre' for future comparision & /or for objectivity should you want to 'intervene' one way or the other at a later date.
Cheers & Wish you Luck either which way you want Dame Luck to smile on you!
