Debating...test?

I'm on the bc ortho-cycline. Been on for 2 months currently in the 2nd month pack.

I have been taking it haven't missed a dose yet. But ever since week 2 of this pack which started on 1/10/16 I have felt like crap (see symptoms)

I'm debating on contacting my doctor and asking for a different kind/brand.

But I'm wondering if I should take a pregnancy test first before contacting her cuz of my symptoms.

Which are:

Currently everymorning feel nauseous (to the point where I'm gagging just trying to take a drink or take my meds), I have slight fatigue, cramps, my boobs have been sore to where the point my bra and just water from the shower hurts them, my mood has been all over the place... I have to bite my lip a lot more than I used to even with my medication- Lamotrigin that I have been on before this new bc.

What do you think?

Should I test or am I fine not testing?
