9 dpo Metallic or bloody taste in my mouth

Mrs. S

This morning I had a horrible bloody/metallic taste in my mouth that lasted a few minutes. It was followed by a slight watering of my mouth. I'm wondering whether this is a symptom or just a cause of taking 1 tablet of prenatal with iron last night (first and only time taking it). I got a sample pack of Citranatal 90dha from my OB so I tried it out.Please share your experiences.
