Hi. I hope I can help. In young women ovarian cysts are common, even on oral contraceptive pills. Your doctor ordered an ultrasound to look for a cyst as the cause of your R sided pain. He likely put it off two weeks to see if the pain will resolve on its own, as most cysts go away even if nothing is done. If the cyst is very large, has solid components (which is less likely and seen by ultrasound), or is painful enough to interfere with your usual activities, he may advise a same day surgery called laparoscopy to look and treat the cyst. Don t stop your pills as women off pills have more cysts than women with cysts. If the pain becomes severe or you have a fever and vomiting, see a doctor, even if you have to go to the emergency room. Sometimes R sided pain is from the appendix, not the ovary, though again, its less likely. If the pain is from a small simple cyst (simple means all fluid, no solid parts) then motrin,or other over the counter pain meds, and time should resolve the problem.The blood in your urine may be because of the vaginal bleeding, and should be rechecked when not bleeding at all. Even if it is still there 85% of the time it sin t because of any problem. Some people spill a few blood cells into their urine without anything being wrong. Your doctor should follow this up after the pain is gone. Some testing might be needed if it continues to make sure your kidneys and renal system are all OK. A lighter period is not necessarily a problem on pills, it is likely to occur the longer you are on the pill, however if this is very different for you then one other test is important, especially if you have missed pills a few times this last cycle, and that is a pregnancy test. You can do one your self with a first morning specimen of urine, but if it is negative, you should have the doctor follow up with a blood test, which picks up HCG, the pregnancy hormone before it is found in the urine. If positive you will need a few more blood tests to be sure a pregnancy has not grown in the R tube instead of the uterus. That can cause pain w/o fever, and light bleeding. It usually requires surgery to treat, though there are also medical options if it is very small. So, to give you a summary. Likely this is a minor problem that will go away on its own, but its important to return to the doctor and let him make sure there isn t a less likely, bigger problem starting. The earlier you know for sure what is going on, the simpler the treatment.
