I had my progeterone levels check and they were in normal range, could I still have low progesterone

after I had my son my body was not same and he was my seccond child I have lots of syptoms of low progesterone, but when I got them tested they came back in normal range, with my period it was .5 and with out my period it was 7.1. My doctor told me that was normal, but why am I still having these syptoms. Dry eye, ache and pains allergies, heavy menstual period with clots, we put an IUD in and it is still heavy and cloting, Fatigue so bad I am tired all day. I had my testoterone levels check and my thyriod, also my cortisol levels were also normal. I am glad all of them came back normal but I am still stuck with all these syptoms it is very frustraiting. I just had another baby in september so I am not sure if it could be my Progeterone levels. Any advise would be great appreciated..

Thanks,
Jenn
