It's a little hard to tell without seeing the whole rear section of her. If it was right before she went on fast, it could just be her digested meal really pressing the follicles out. Given the timing of her fast, I'm inclined to think there is a strong possibility it's that vs ovy, as mine will usually go into fast for weeks before ovy, but I wouldn't completely dismiss it either. See how this pairing goes and if you don't get a lock this time, it very well could be ovy.
