Need some help here...

Er

I've been talking seasonique birth control pills for two months and I stopped taking them a month ago... I still got my period last month on time but this month I'm late a week and I'm thinking it's still birth control..

Ladys I know some of you are going to say why don't you just take hpt but I just can't I don't want to get upset seeing an negative test... Plus I don't have that feeling in me that makes me feel I might be.. So my dilemma is has anyone had this effect on them after getting off birth control... I've never been on birth control before..
