Pregnacare is not for induction of ovulation, it is a supportive medication
. It is true that it is too early for ovulation to occur, but taken that you had a 28-day cycle this time, you could as well be ovulating early-that is one possibility. You should consult your gynecologist and get a trans-vaginal ultrasound
done to see if the ovaries and tubes are normal; you may also need a local examination. You may also exclude renal causes as similar pain can be observed in urinary infections, presence of calculi etc. Wish you good health.
