I had sex last night, and this morning i had heavy bleeding that somewhat stopped later on. also i have been dizzy and nauseous. should i get checked

Ruptured cyst?: We know that dizziness and nausea can be caused by a variety of things, but i wonder if you might have had an ovarian cyst that ruptured (broke) during sex. An ultrasound done soon may show fluid in the pelvis if this is the case. You didn't mention where you are in your cycle or whether you think pregnancy could be a consideration. In any event, get evaluated! lgromkomd.
