Ovulated late? Late AF? Still BFN. Help!!

Jessica • 32, married, mother
Hi ladies! So I woke up at 4:30am and took an HPT with fmu, I don't know if I see anything but still no definite BFP. I need some love from you ladies. According to Glow's chart, I'm at 15 DPO. My last period started 12/19 but Glow predicted that AF was due on 1/16. It's 1/19 today and still BFN. I don't know if I ovulated late or what. I didnt use OPKs when TTC. I just feel my body is shouting symptoms that I have a work of miracle inside me. I don't want to assume but I just feel it. My husband and I are planning to retest on Saturday 1/21 with 6 Days Sooner First Response and a Digital Clearblue. I really hope we get our BFP on Saturday even if I had 5 BFNs using cheapie strips (from 99cents store). Does anyone of you experience this? Having BFNs then a BFP using branded HPTs? If I ovulated late, I hope the 6 days Sooner First Response will show an accurate result. Here's my test this morning. Judge it ladies. Opinions are welcome and will be a great help. Thank you! Baby dust to all of us!
