need help please!!

Hello everyone.
Please if you can help me do so. I am so confused. Period was due 2/22 had literally pink dots (spotting) took pregnancy test got a faint line. Next day again very light spotting took another pregnancy test  and again got a faint line. Now today the 24 it isn't spotting anymore looks more like a period but not my usual period. Just took another pregnancy test and again I see faint line. Can I still be pregnant or am I getting false positives. I don't want to lose hope. 
Please help me. 
Thank you!!
