ADVICE NEEDED LIKE NOW!

For the past three days I've had back aches, cramping, headaches, dizzy spells, urination every 15-25 mins regardless of drinking anything, loss of appetite, and tired but not too tired obviously bc I can't sleep, VERY vivid dreams, and in the morning I wake up with cold symptoms that go away within the hour, and ((TMI)) but slight to heavy milky cm.. I know it's not a kidney or UTI type infection bc the symptoms that point to those thank god aren't here in the most sensitive areas, no sore BBS . I can't pin point anything ... I'm only 7 DPO. Some PLEASE give me some advice here!
