Sounds like menopause. Maybe look into taking vitamins and supplements like Evening Primrose oil or Black Cohesh. Talk to your doctor. If you're tubes were tied then you're not pregnant....
Hi I doubt if your pregnant.The gaining weight is normal though with going through menopause.The discharge with fishy odor,try a douche.If you do not have no itching or burning sensation that is.If you do have those symptoms go to the doctor.Feeling sick and queezy at your stomach could be a viral or your nerves can make you nervous.If you feel you should go the doctor then do it,you know your body better than any one.I hope this information helped.Take Care TNT406.
