A little scared. TwoX help/craziness dismissing (or not) needed

So I'm crazy. But I've has some weird periods lately and its making me really scared that I'm pregnant, last month I had two periods closer together than normal because of a hiccup in my pill taking and then my mom freaked me out further by telling me that's how she was when she was first pregnant, so I did a whole pack that ended a few days ago and now I have like no blood at all. A little but still, its all making me feel worried. Im pretty sure I've used condoms anytime I don't feel safe just on the pill but we still use condoms almost everytime, and I've taken plan b before for a broken condom so I'm fairly sure if I felt like I needed it I would have taken it. I'm just going a little crazy and mostly confused on the periods weirdness. Anybody else have a similar experience with the weirdness? Could it just be super light because of last month? Anyone want to tell me that its just stupid? Thanks y'all
