The confused waiting

Jessica

This is my first month TTC. I had 3 girls when I was 19-22. I am now 34. I started tracking my cycle in May to get an idea of when I would be fertile. My husband is sterile so I had to use a donor. The app said I would ovulate on the 11th of August based on my cycle data. I inseminated on the 8th and the 10th as I could only do two. I am now 19dpo or 5 days late for AF. I got a BFN yesterday and still no AF. I wonder if the TTC is making me late or if it is still possible to get a BFP. I suppose I will find out sooner or later.
