I have a problem

Cassie
Just read an article on low progesterone and fertility. I already have one daughter who is 18 months and one angel baby as of two months ago. With my first pregnancy I was put on Progesterone right away and with my second pregnancy I think I waited too long to go into the doctor and get seen, my progesterone was too low to keep a healthy pregnancy by 6/7 weeks. 
The article I read states that you can spot a lot of health issues during the luteal phase. One being progesterone which you need to conceive. Healthy temps are above 98°. I  only have one temp above that, and two directly at that temp. The rest are "too low".
I looked at my previous month's temps and they are too low, too. 
Feeling defeated today. 😭😱
Ps- glow changed my ovulation range and predicted period to show it's like a week later than it should be because I left my window open one night. I O'd on CD15 and AF is due 4/29.
