Right side pain /low belly almost by my hip. very uncomfortable pain. back pain as well. tender abdomen. light spotting 2days now. ?

Rule out Tubal Pregn: Your symptoms are worrisome. Pain like you have requires medical examination from your doctor ASAP. If your menstrual period was delayed by more than 2 weeks, then a tubal pregnancy is one serious consideration. This requires immediate examination by a health care worker. If symptoms are getting worse go to the ER over this weekend for a medical examination and testing. Good luck.
