Im a 39 year old mother of 3. My middle son has downs syndrome which is simple in itself its the life threating medical problems he has had. Their dad and I have been seperated for 6 years and I work evn/nigh 730or 830 pm -4-5am so that I can be with my children during the days when they are off school and then in the summer as well. My periods have been pretty steady with every other month being lighter but more crampy. Until recently, the last 3 months I have gone from changing every 2 hours or so to not having to even use a tampon or much more then a liner. I had a tubal with my last child so im pretty sure pregnancy is not an issue. I don't get much sleep as I have been working a part time job to make it through the holidays. The relationship I am in Im not so sure that its meant to be and I guess Im stressing over weather to break it off as well. Im guessing the combination of lack of sleep and stress are causing the lack in periods. I have frequent heartburn but could just be getting older and maybe the frequent urination has to do if I have caffiene but combined they had me leary of what is going on with my body. Any help would be greatly appreciated.
