Advise please. 13 days late but have had multiple positive ovulation tests.

So this is my first month of bc and we are trying to conceive. I had a period right after i got off of it. We have been bd a lot and I’ve been tracking my ovulation. I understand that bc can delay ovulation, af and many things but i also know of people who have gotten pregnant the first month. I am currently 13 days late according to glow and i got a positive ovulation test 2 weeks ago. This is from today. I took one this morning as well that looked the same. I’ve tested so many times and haven’t seen anything really and i thought i would just use these instead of wasting the money and getting disappointed. I have heard people say that LH And HCG can not be differentiated so i was wondering if anyone has went through something like this. Please no negativity.
