I think I'm pregnant?

In the last week, I've had light cramping, kind of like a period, but it's more like a flutter than a cramp? I dont ever have light cramps, theyre always stabbing pains considering ive got multiple ovarian cysts. Sore breasts, backache, fatigue, moody. It would be too early for a test but this doesn't feel like Pms usually does for me...
