TTC and getting BFN

Maria

So my thing is I’ve been off my bcp in march April I got a period and may I didn’t get one at all so I got it June 1st so based on my glow calendar I was suppose to start my period on Tuesday and now I’m 6days late what should I do I did test on Thursday and a vfl of a positive and tested today and I see a negative! My question is why doesn’t in July show me when I’m suppose to ovulate ?
