My mum conceived both me and my brother straight away too. But took us 9 months.
My temps are low too. From what I can gather, progesterone doesn't necessarily correlate with temperature. I have a poor temp shift and lowish temps and my progesterone levels was above normal. I have also seen chart of ladies with low progesterone who have high temps and a good temp shift.
Low temps 'could' indicate a thyroid issuer esp if you have other signs of hypothyroid but again. My thyroid hormones were fine.
Have you tried the Sperm Meets Egg Plan? Basically bd every other day from cd 8, use OPKS from cd10, continue bding EO day until + OPK, Bd that day and the next 2 nights, have a day off then do one more night for good luck.
I found it very beneficial learning to read my CM/CP then I knew when I needed to bd. I think the 2 days leading up to O day are the more beneficial.
Really try not to worry. Our chances of conception are about 20% with perfect timing. It really doesn't mean anything is wrong.
Good luck.
