What do you think?

Last Thursday was the last day of my month long period.. Saturday and Sunday I spotted just a little and today I took a pregnancy test because I haven't been feeling right. I think I took it way too early but I can see a very very very faint line. I can't tell if I got it on picture because the top of my phone is broken. But I definitely see a faint line. Advice please. Should I wait to retest or should I call my obgyn? My cycle is so irregular that I can never keep track of it. TTC since January.
