I will be 31 in a fe months. I have 2 kids, and have had my tubes tied for nearly 9 years now. i've noticed since last year, that my periods have been getting very irregular and i could never tell when they were going to sneak up on me. so i have had to start keeping track of them. i've been to have ultrasounds and taken progesterone. they said it was horomones. so i let it go. well this is september, and i've noticed that i've only had 4 periods this year. January, March, May, and July. i've skipped August, and most of this month, so far. i've noticed the past 2 weeks that my back has been hurting and my breast have been very sore. i thought, i've done something to make them that way, i'm not huge, (about a D) and they hurt when i walk around without a bra on. it kills me to bump them with my arms or anything. i've also noticed that i'm going to the bathroom more frequently, i'm having alot of headaches, and my lower back has been hurting alot. i'm usually cold natured, but last night, i woke up sweating, and that's not normal. my whole body was sweating. i got up this morning and took a pregnancy test, which came back negative. everything that i look up with these symptoms, comes back that it could be a pregnancy, so I have no clue what else could be wrong with me, since i'm not pregnant. any suggestions would help ease my mind!!!
