Hi, three weeks ago, after my period, I found droplet of blood in my underwear and something long and clear like mucus, I had pain in my lower and upper abdomen. I had check up. Doctor said it was Ulcer that causes pain in my upper abdomen and Urinary Tract Infection in my lower. He gave me medicine for ulcer and UTI, the pain is gone but after like 2 weeks or so, I had pain in my right and also in my lower abdomen and also when I am peeing, and after a few days, my period came back. I want to know what causes the droplets of blood, the long, clear mucus, and all the pain? And is it normal to have period twice a month? Thank you.
