Sudden discomfort during ovulation...?

For the past two months I own noticed that right around the time of ovulation I become incredibly itchy on the outside of my vagina. At first I thought it be a yeast infection. I just so happen to have my annual exam end month when the discomfort appeared for the first time and the dr tested for yeast and it came put money on neg. It happened again this month as very well. Is this one of those cyclic changes a woman go through or do I need to be more concerned? The discomfort starts at almost day 10 and disappears around time 18.

Sorry if that was gross.

Thanks!

I enjoy a little infection on my disappeared boobwhat could it be?

Hormonal changes as we walk through life can create a sensitivity to our own bodily fluids. There are creams out here that will help.
It could be a vitamin less (vitamin C and calcium/magnesium are important to carry on internal balance) - if you've changed your diet lately that could be a contributing factor.

Is it my period and if so.?

Certainly could be. If the iching is accompany by redness and inflamation, I would find your doc to check it out. Otherwise, you can try some of the over the counter topical femanine iching ointments out in attendance. In the interim, an ice-filled rag should help out take away some of the discomfort.
Good Luck!
