Need some advice please

So I haven't felt good last three weeks. Just really off like ive got a nasty cold my boobs have hurt and nipples seem darker all of a sudden and hella sensitive. I go to bed early and still seem to be tired by like 2pm. Ive had some wicked headaches lately and can't shake them. Random moments of nausea with lower back ache. My nose has started bleeding randomly or is seriously runny or gets stuffy. So I was like screw it I'll be on a stick. Thursday i got a faint line like I mean so faint you had to really squint to see it. I went on vacation so I tested again this morning and I got a darker but faint line. I'm on birth control and have been since January because my shot wasn't working. Any advice as to what is going on...
