stopped taking bc

I was on the Lolo pill and it was causing me to have 2 periods a month. So I stopped taking it. When I was on it I took it at the same time everyday and we used condoms. I stopped taking it over a month ago (we haven't had sex sense I stopped taking it, he's been out of town) and still have not got my period. I took a pregnancy test and it came back negative. I don't feel pregnant but it's making me nervous. We don't want another baby right now 😬😬
