Hello and welcome,
Skipping periods once in a while is not uncommon, especially in the perimenopause - the many years before a woman actually goes into menopause.
Since it has been 2 months since the beginning of your period and you have had negative pregnancy tests, this is what I would recommend; by the third month, if the period still has not come, is to go for a blood test called FSH that will show if the absence of the periods is due to the ovaries not producing hormones and eggs - that is perimenopause; or it will show that your hormones are normal but there is something else interfering with your cycles.
Some causes are medications, high blood levels of prolactin, thyroid hormone (both hi and low interfere with regular cycles), stress, significant weight loss and the like
But the simplest thing to check first is the FSH (blood test)
Hope this will get you started...
Feel free to ask any more questions...
If you have bloating or increase in your abdominal girth where your pants or skirts do not fit and if you are worried about say something going on with your ovaries, the test to do would be a pelvic ultrasound, where they actually take pictures, measure the ovaries and the uterus.
With the pain being in the upper abdomen, it is not typical for gyn origin, so from what you described, I am not suggesting that you have the symptoms of ovarian or uterine disorder
Let me know...
Yes I understand.
You will probably end up seeing both the gynecologist and the internist; I would recommend seen the gynecologist first, who, hopefully will order an ultrasound for you to check the ovaries, and if that is normal and your hormone levels are where they should be, then you could go to the internist.
If you do it vice versa, it is almost certain your internist will advise you to see the gynecologist first then go back to him or her after confirming this is not a gyn problem.
Much luck to you, let me know if I can answer any questions to the best I can, thanks
