Yes, you could still get pregnant! Progesterone does not peak until about 7 days past ovulation, so 2.03 on the day of your LH surge (which is a day or so before ovulation), does not mean your numbers are low. Good luck!
Your progesterone level drops before your period. Mine usually goes to .5-1. You may be pregnant but it may be very early or you may need to be put on progesterone medication such as prometrium which is what they put me on because I normally have a low level and won't support a pregnancy without the boost.
