Ay sis, yan talaga ang ovulation pain na dinaranasan ng marami sa atin, the cramping on one side especially is actually super normal, kaya don't worry! A few of my mum friends swear na it's their most reliable sign ng ovulation, more accurate pa kaysa sa apps sometimes dahil ang body natin ang nagdidictate, hindi ang calendar. The egg white discharge mo ay dead giveaway rin talaga. Now about the pregnancy thoughts, hirap talaga ng waiting game, pero honestly the cramping and discharge sounds more like textbook ovulation to me kaya I'd say just wait for your period and test if you're late, yung line will tell the truth!
