I m 26, and suffer with bad PMS. Lately my period cramps have been getting worse - I ve had three episodes this year where they were so bad that I nearly fainted/vomited. Up until this year, I ve always had a very regular period, heavy on the first day and getting lighter over the next three or four days. The last two months, it s started with spotting barely anything, then the second day is awful, and then by the fourth day it s finished. Last month I worked out I bled 60ml just on the second day (I was emptying my cup every hour and a half), but overall it was only about 80ml, which I understand is still a normal amount of blood loss. I m not anemic, but I am getting worried now by this change in my periods. Could I be progesterone deficient? I ve read this is a possibility. I should add that I am sexually active, but always use condoms.
