Does it sound like I have low progesterone or just bad timing ?

Im 20 bout to turn 21 and I had a chemical in July at almost 5 weeks I spotted for a week before I finally Mc. and this month the day after Christmas I found out I was pregnant my lines weren’t getting darker and today I took a test when I woke up bc I was spotting and it was a BFN! Now I’m having full force af😔 Can spotting like Iv been having with my chemicals be from low progesterone❓❓❓And if you had low progesterone what were your symptoms ?! I feel like we’re just gunna give up for awhile and I might get checked to see if something’s going on
