If I get multiple positive OPKs, could it mean multiple ovulations?
I usually only get one positive OPK, but this cycle I got two days of
positive OPKs. Did I ovulate twice? Does that mean if I get pregnant it could be twins?
Multiple positive OPKs are not associated with multiple ovulation. Many women get more than one positive OPK for a variety of reasons. Sometimes they catch the surge at the very beginning and the very end, spanning two days. Sometimes their body starts an LH surge, and for one reason or another, it turns out to be a false start.
Multiple ovulation occurs within a 24 hour period. According to Taking Charge of Your Fertility (by Toni Weschler, MPH), it is believed that multiple ovulation occurs as frequently as 5-10% of all cycles. Most of the time, however, both eggs are not successfully fertilized or implanted. Only about 1 in 60 naturally conceived births are twins.
There is really no way to identify multiple ovulation with OPKs, charting, or fertility signs. Some women claim they feel ovulation on both sides and believe that indicates multiple ovulation. This may be true, but ovulation pain doesn’t always correspond with what is going on internally. Frustrating, eh?
So don’t go buying two of everything yet, that’s all I’m saying…
