This is a nightmare

My pregnancy is a suspected ectopic. Had the methotrexate injection a week ago. Numbers decreased at day 4 but stayed the same between day 4-7. I’m in pain and just want to feel normal. I don’t understand why they can’t just go in surgically to find where this embryo is growing instead they’re having me wait 3 more days for another blood draw. I just want to feel like myself again. I tired of the sharp pain in my side, the urge to crap with nothing, and feeling emotionally defeated. Please share your experiences. I’m terrified this thing will rupture before I even get another dose of methotrexate.
