.2% Chance, Is My Boyfriend Superman??

Grettings ladies,

i'm starting to become quite worried here in michigan.
I've been on ortho tri-cylclen lo for 4-5months now,
i've taken it religlously every morning, but i've gone through
5 of my seven green pills and have yet to see or feel a drop of menstruation.

The second to last time my boyfriend had sex he was rather full, lol
and the day after my chemistry changed.
I became dryer than usual, which I dealt with.

Now however i've had violent mood swings, a change in appetite
and I have noticed my cervix has dropped low inside me and is
uncomfortablly far down my vaginal canal.

I may be too into myself but I also noticed increased blood flow to
my lower half. Seeing as I am anemic i've also been having to
take twice as much iron supplement to prevent dissiness.

I'd like a opinion on whether I should bother with a pregnancy test
or not and do I need to stop taking my ortho pills for
it to be an accurate result?
