I may have ovulated during my period

Well, I'm not sure when I exactly ovulated, but I know I have ovulated before today, cycle day 10. Looking at my chart, it appears that I may have ovulated on cycle day 3!!!! I'm so confused. I didn't even think that it was possible to ovulate during your period. On cycle day 3 I had 4 antral follicles. They don't start to test progesterone until day 10. I have read that you can have antral follicles during your luteal phase, so it's possible by then I ovulated. I went in today for my cycle day 10 ultrasound and they told me that I had no measurable follicles, but I had 5 of them. I was confused because usually by cycle day 10 I'm ready to trigger. Well, a couple hours after I got home the nurse called me to say that my progesterone was high and that I already ovulated. I don't know what is going on or how this is even possible. I am very worried about myself and really think that there is something desperately wrong with me. Mind you I did take a very high dose of Femara last cycle which could explain why I ovulated super early this cycle. Maybe it lingered into my next cycle? 

I'm a bit worried because I'm going on a trip for 8 nights on January 19. I was thinking my cycle wouldn't be so weird and that I could control AF so I wouldn't see the witch during my trip, but it looks like I may be out of luck. The nurse told me to come in tomorrow to get progesterone and then come in 2 weeks for a pregnancy test. I don't think I have a chance this cycle. I'm going to take progesterone for 12 days starting tomorrow. Hopefully, it will delay AF and I won't get it when I'm away. We are going on a Caribbean cruise and I want to spend my time in a bathing suit and not stuck in my room the whole time rocking back and forth in pain. AF is torturous for me.
