A little assistance, please!


Okay ladies, this is only my second month using OPKS and <a href="https://play.google.com/store/apps/details?id=com.glow.android">tracking ovulation</a>. My cycles are usually about 31-32 days; last month I got a positive OPK cycle day 18. Today starts my fertile week and I've been having a little cramping and a lot of EWCM, it's cycle day 15. I figured I'd take an OPK just to see and I got this:

Two questions:

First: would you say this is positive?

Second: is it normal to ovulate at such different times each month? I mean it's CD15 and last month it was CD18

Thanks ladies!
