Early short period ?

Amanda

Hey ladies i started spotting brown and clear stringy discharge 2 days before my expected period then started bleeding a little more the next day and then back to spotting on the 3rd day I also kept having a weird twingeing feeling and no cramping . Which is off for me cause I always have severe cramps and always start off with a heavy flow . It's been a few days since then and had some more stringy discharge with a little blood in it . Since then iv been super nauseous and tired could I be pregnant ? It sure feels like it but I think my mind is playing tricks on me :/
