Please help me - I don't know what's going on...?

It would be too soon to feel a baby moving or poking but still you could be pregnant. The light period you described could have been implantation bleeding. PCOS has a bad habit of messing with the results of home tests so see a doctor for a blood test. If you aren't pregnant talk to your ob/gyn about some fertility testing for both of you and possible fertility treatments. The simplest and cheapest one is clomid and it works rather well. Good luck.
