Okay... I am so confused No insurance cant get into the doc at the moment.

Okay, So I was pretty sure I was pregnant. I have all the symptoms and was planning on going to the pregnancy clinic in my town. I'm 21yrs and trying to conceive. I had a missed period. Now I am cramping every once in awhile, and bleeding, bright red-pink. I have taken a test but it was very faint I couldn't see anything. I thought it may be implantation bleeding or a miscarriage but I'm not sure. It got heavy ish earlier now it is light again. Almost stopped and light. What in the world... Idk If I should take another test or go to the E.R.
