Could I still be pregnant? Please read?

For the past 2 weeks I've had a few pregnancy symptoms. About 4 days before my period was due I had very light spotting with brown blood that only lasted a few hours. Then I missed my period so I took a test the next morning but it was negative. I started my period a few hours later. It was heavier than the spotting but not like a normal period at all. The period only lasted 2 days and filled up a total of 1 pad. It had a flow like a period but it just didn't have as much blood (sorry tmi). But now it's completely gone. It usually lasts 4 or 5 days and is very heavy. I didn't have very bad cramps at all which is weird for me. Should I test again? Could I still be pregnant? What do you think? Thanks!
