I'm 8dpo today and I'm wondering if it's possible to get pregnant with low progesterone? My level was 5.6 which is pretty low. My bbtemp is staying well above the cover line still and I had good hope but I'm starting to think I'm out for the month again 😥 so ready to just give up... it's breaking my heart seeing all the pregnancy posts lately.
