%-) Okay so this is complicated sorry. I have had irregular periods since i can remeber and have been on birth control for 4 years. all types still dont regulate it. the past 4 or so months that I have had my period I have gotten really dark brown mucousy think periods for about a week and then I get my red period for about a week after that. I have also been having a lot of pain in the past year or so and after several different doctors they found a lot of cysts on my ovaries, and they think I have endometriosis and am having surgery. but recently i thought that i was pregnant because for one, i messed up a lot on my birth control, then I didnt have an off period. i went the whole month without irregular bleeding and I thought it was weird. it made me think I was pregnant. then my brests were sore, one morning I was really sick to my stomach, i have been very moody, also hungry, and been having some different pain. Then I started about 2 days later than when my BC said i should have and it is now like the first part of the period I have been getting lately, thick, dark brown, but a lot more mucous than normal and has now gotten really heavy with some normal blood. is this normal for endometriosis or could I have possibly have had a miscarrage? I dont know if I should get a pregnancy test just to make sure. Is it possible I could be bleeding from endometriosis and still be pregnant? im very confused and I am just scared something is very wrong with me. Thanks so much and sorry for this being so long.
