Positive Ovulation test on CD 50 😳

Can this test be any more positive.. can i really be ovulating this late in my cycle? I’ve taken 3 pregnancy tests in the last two weeks . All BFN . But then this .. my boobs are super swollen, I’ve got a heightened sense of smell & nausea occasionally. Nothing too big . I’ve been trying NOT to symptom spot.. could an ovulation test pick up HCG? Should i get another pregnancy test or just BD now ? AF is 15 days late .

**took this opk this morning .. still positive & we BD last night. So fingers crossed either way 🤞🏾🤞🏾
