Yes, it happens. That's how fraternal twins exist.
I ovulated on both sides last month, as I could feel it. I usually only feel one side.
|Women may ovulate more than once a month, suggests a Canadian study that overturns conventional views on the human menstrual cycle.
The findings may explain why the rhythm method of contraception is so unreliable and could lead to improved, targeted fertility treatments in the future.
Ten per cent of the women studied released two eggs in the same month. And all the women examined by researchers at the University of Saskatchewan in Saskatoon, Canada showed at least two waves of maturing eggs in their ovaries in the same month.
Traditionally, it has been thought that ovulation takes place only once in every menstruation cycle. A growth wave of 15 to 20 egg-carrying cells called follicles occurs before ovulation. One follicle will become dominant while the others die off.
"It's been assumed until now that women have just one wave per monthly cycle, leading to one ovulation, but nobody has actually carried out detailed analysis before," said Roger Pierson, who led the study. "In fact, all the women in our study had at least two waves and 30 per cent of them had three."
|A note about OPK's: Luteinizing hormone can be measured by ovulation prediction kits (OPK) that use chemicals to identify the presence of LH in your urine. The presence of increased amounts of LH, as detected by OPK's usually means that you will ovulate within 12-24 hours. LH is not released all at once, but rather it rises and falls for 24-48 hours. The LH rise usually begins in the early morning while you are sleeping and it takes 4-6 hours for it to appear in your urine after that. For this reason, first morning urine (FMU) may not give the best result. It is important to follow the instructions of your OPK for maximum results.|
