I've had eight faint positives and last couple of weeks I've had bloating light cramps lower back aches nausea and a metal taste​ in my mouth?

Advise eval. Hi Sorry hear you have been suffering from health problems. With as many symptoms you've been having, I think you require an in person evaluation from a local physician. Fainting spells and nausea are difficult symptoms to diagnose and require a much longer discussion than we can provide on the public HealthTap forum. Hope you can get seen soon.
