Interesting news and a ?? for the pros out there...

I had a very thorough medical exam this morning (totally not related to TTC but got some news) and as part of my exam, they did a baseline ultrasound on all my female organs.  One of the ultrasounds was vaginal for a close up look at my cervix and ovaries.   I asked the technician if she could see evidence that I'd ovulated as my temps have been up the last two days and I'm thinking I may have ovulated either CD 19 or CD 20 (I missed temping on the CD 20).  I'm currently on CD 23 today.  She said that she saw a ruptured follicle on the left ovary and that there was a mature follicle on the right looking ready to 'blast'.   I felt a little silly but I asked if that meant it was possible that I could ovulate twice in one cycle a few days apart.  She told me that she thought it was possible and that I should check with my doctor.

Is that even possible?  I mean, I know fraternal twins are the result of 2 eggs being fertilized but can the eggs be released a few days apart and still be viable pregnancies?

Google is no help .  There are camps that claim both sides of issue.  Yes it's possible.  No it isn't.

Regardless, I'm planning on keeping the bed warm the next few days at a minimum... just thought I'd ask!
