I got BW done at cycle day 3 and cycle day 25. Per my OBGYN. I have a very typical / normal 28 day cycle. I did take OPKs, got a positive on cycle day 14. My progesterone level only came back at 2.7. Doctor said 'it is on the low side but she had no concerns'

I've been TTC for almost 2 years. This past March i had a miscarriage. I did some googling and I think that number is very low. And is the reason I'm struggling with TTC. I also read low progesterone can cause migraines and bloating which i stuggle with both. Anyone have a similar level and got pregnant or was prescribed anything?
