Ladies I already ovulated I got 10 days till af. I can't get test till Sunday so I heard about using opks. I already ovulated. I know it's not accurate but my lines are getting darker. I've been getting lots of watery cm which is weird since it's either dry or creamy. Also I've been having small amount of nausea, Heightened sense of smell and small cramps.
