hello im joanna self and im 38. i have not had a period for months and i have tested for pregnancy and im not. i am over weight and active. i work 2 jobs that i walk around and bend and stoop and lift and stretch all day except for when i have to travel from job to job. could my weight be whats causing my missed periods. i had irregular periods before ever since i had my daughter and shes 6. I gained alot of weight during my pregnancy with her and i lost some weight after but currently still am overweight. im 5'9 and weigh 245 and back before i got pregnant when i weighed 150 -180 i didnt have problems with my periods. for 6 years i have had periods that would skip a month or 2 but not this long is been probably 5-6 months. i sometimes get this full feeling like im getting ready to start and cramping but nothing ever happens.when i did have my period it would be really heavy especially when i skipped a month or 2. even though i work 2 jobs they are both part time of 10-30 hrs combined and i have student loans and debts im paying on so i dont have insurance and dont make enough to pay premiums for med insurance or doctors visits. so i dont go to the doctor that often. theres no cancer that runs in my family as far as i know but im really scared cuz im worried this has serious health risks plus i wanted to get back regular periods and lose this weight so i can be healthy again and have another baby. i am planning a change of eating habits and beter diet i know what need to do on that and i am looking for a treadmill so i can do more walking at home. can someone tell what i can do? what is wrong with me?
