Can Someone Help Me Out??

** I DIDNT POST THIS TO GET ATTACKED. SO I ONLY WANT NICE AND HELPFUL COMMENTS. KEEP THE RUDE ONES TO YOURSELF.** 
So my period is 43 days late. The last time I had sex was sometime between January 7th and January 13th. 
I've had pregnancy symptoms but negative tests. The last time I tested I thought I saw a very faint line but came to the conclusion I was insane. 
So could I still be pregnant??? 
UPDATE**
I did read up on some other ladies stories and they ended up being pregnant.
