Need advice

Hi ladies so I need advice or help but I'm supposed to ovulate today according to app but I took an opk on the 5th it was positive so a few days ago just to check before bed I took 2 more they were positive and I guess im 12DPO should I take another opk tonight just incase? Also my boobs are tender, I have been having nausea on and off for a while now I feel more tired I've cried at stuff on shows I've watched and knew what was gonna happen and I haven't cried at the scenes before but I'm worried about testing too early and according to glow AF is supposed to be here in 11 days what do y'all suggest or may know what's causing this
