What is the cause?: There are many causes of these symptoms. One is pregnancy. That is easy to test for- could it be the cause? There could be changes with your hormones for other reasons. Either it could be from the ovaries or some other location. If your home pregnancy test is negative, could be time to see the family doctor, or OB/GYN, or endocrinologist, probably in that order.

See details: First make sure you're not pregnant. If negative significant weight gain by itself can interfere with your menses. Your symptoms may or may not be related. There might be more than one thing going on. For example this could be related to thyroid dysfunction. There might be a diabetic component. Polycystic ovarian syndrome is a possibility. You need a proper examination and testing.
