Unprotected sex jan 11 about 2 to 3 days before ovulation. Negative test jan 22 and jan 31. But from jan 21, all sorts of symptom appeared. Not sure if just pms or pregnant. New / first time symptoms would be heavy, tender and full breasts, heartburn shortly after eating, nauseous but no vomiting, aversion to ramen and burger (i've loved both all these while), and panting a bit after climbing up about 5m of stairs. Usual symptoms which are present now too are bloated/gassy, dizziness and headache. Period supposed to come jan 28 and today jan 31 there's blood which I think is my period but it's been a few hours and usually my period is heavy for first 3 days from day 1 plus strong cramps but nothing at all as such. Pad isn't fully filled too. Mild cramp before the bleeding and now no more cramp. Should I wait a few days and test again or is this period? Then what about the new symptoms?
