Confused with my OPK

Round 4 of clomid.. So is my opks from yesterday positive .? It seems like last month it was way stronger and it was confirmed I had a strong follicle. This month no sonogram was done so I’m kinda just guessing . I did and still do have this cramping feeling early this morning and now on my pelvis area mainly on the left.
