Any chance for pregnancy?

last period start around July10. Today (July 25) should be the date around ovulation, but feel vaginal dry but no discharged as expected. This is the first time that this kind of thing occur, which scare me because I found a some (NOT a lot as expected for ovulation) vaginal discharge around July 21, but I thought that may be the leftover of sperm since we ML around July19-20. Since there is exceptional vaginal dryness today , so I think the ovulation may be done around July 21 in advance? But there is just a little egg white-like stuff not a lot like before, So any chance for pregnancy? Thanks for any reply!!!
