About 6 weeks ago I had sexual intercourse for a week straight without protection. A few days later I started my period. It was a light period but 5 days long, my average length. After my period my Vaginal discharge change fast. It was kind of thick and white. The smell was matallic. I started to have symptoms of pregnancy. My breast hurt really bad, I was fatigued, nauseous, headaches, heartburn, lower back pain (although my back has always hurt but its now a little worse), and some foods started to taste weird to me. So I took a pregnancy test about 2 weeks ago (about 4 weeks after sexual intercourse). It was negative. Then I started my period again 7 days ago. The first day was VERY light, the second day was heavier but it was average. The same for day 3 and 4. Although my last day was EXTREMELY light. Yesturday I had no bleeding. Although today I found fresh blood on my toilet paper. It was only a little. So I took another pregnancy test in the afternon but it said negative but the second line that would tell me if I was pregnant or not was EXTREMELY faint but I could see it. Does it mean anything? May I be pregnant? If not my does/did my vaginal fluid smell like metal and look white?

It's always best to take a HPT using first morning urine. Also, make sure you read it within the specified time of the particular test. False negatives are common, but false positives aren't if you follow the directions exactly.
