unexplained bleeding hello. I am a newly wed and not using any birth control methods or protection. before around 4 days of my expected menstrual period I saw some vaginal bleeding., on that same day we had intercourse. it was bright red but was not heavy at all, no smell, no pain except some cramping but not so severe as when I have my period so I didn t need medicine to relief the pain. however I needed a pad because the flow did not stop. I experienced also severe lower back pain and fatigue at the first day. Today is the third day. on the second and third day I feel completely normal, the back pain became better and the flow is about to stop. I am afraid to tell my mother or someone from the family because I don t want to worry them if it s nothing. Today I am supposed to have my regular period which usually lasts for 6 days. My last period was on 17 July and the next one usually comes 2 days before the prior month, so which means it s today the 15th. I am a 22 year old female, 48 kg=106 lb, and 162 cm=5 ft 3 in. I am also a patient of a chronic inflammatory bowel disease (crohn s disease) since 2001. I take 1 tablet of Pentasa 500 mg daily, 1 tablet of Imuran 50 mg daily. Also my aunt, a gynecologist, adviced to take 1 tablet of folic acid 1 mg daily as it would h,elp in pregnancy. Thank you so much and hope to find a reply from you soon. If you have any questions or need more information, please don t hesitate to contact me. Thank you again.
