Anyone know anything about progesterone?

Crystal

I was told by my OB that my levels are at like 5 so I would need help conceiving. My mucus around ovulation is thick and creamy but not clear or stretchy..I want to level myself out but unsure how other than taking these pills. Anyone that can help me understand all of this or other options? Should I take an ovulation kit to see if it comes back positive? I have one kiddo but curious how I became infertile.
