Ovulation problems

Jamie💋 • mom of 2 Boys on earth, ❤️ 👼🏻 3/9/19 👼🏻 1/2/20 👼🏻 4/14/20 🤰🌈 Due 3/2020
I have a very longggg, but regular cycle. Its 50 days long with a period of about 20 days. I know, its terrible but the only way i can regualte it is with birth control, and i cant take that while ttc. I have a 13 month old right now and my husband and I are ttc baby #2. It's been about 6 months since we started trying because we knew it would take a while to get pregnant. I started taking ovulation tests about 2 months ago but every single test I take is positive. Before anyone asks if I'm reading the test right, I am. Both lines are equal in color within 3 minutes. I'm beginning to think I can't get pregnant again. Has anyone else ever had this problem with ovulation testing? I need to pin point ovulation because of my long cycles and it's just not happening when I show an LH surge every day. Help!
