Low progesterone

Has anyone else had problems with implanting because of low progesterone. I was supposed to be 5 weeks yesterday and had a transvaginal ultrasound and there was no sac. They took my blood and they called back today and said it’s most likely a chemical pregnancy because my Progesterone was only .7 and my HCG was 12. I just took another First Response and the test barely even had a line, it almost wasn’t even pink anymore. So I’m curious as to if you had low progesterone and how they went about correcting it. I would like to talk to my doctor about it on my follow up appointment on Monday.
