You should wait until your levels zero out before taking Amy folic acid, including prenatals. It can dull the effects if the methotrexate. I too suffered an ectopic in October 2011, and had to take two doses or methotrexate, so I know how impatient you feel right now. You just want to avoid complicating it any further.

Update. It turns out that my count did go down when I went to have blood drawn again. Right now I'm at 308. This is taking sooo long. I have started back taking my vitamins with an extra 800mg of folic acid. Everyday. Im not patient at all.......
With any miscarriage it is not super uncommon to have levels continue to increase. Methotrexate is given to help the body naturally expel any tissue, etc. Even though it may be out of your tubes, it is possible that a sac developed in the uterus or that your body didn't completely expel everything. Even with etopic, it is possible (and not that uncommon) to develop an empty intrauterine sac. It's good they are following up. All the best to you, and I'm so sorry for your loss.
I had an ectopic 1/2012. Hcg levels went down after two shots of methotrexate. My dr said if they go up or stay the same after the two initial shots that usually means you didn't expell the fetus/sack and theyll usually give a third shot or do a d&c.. My symptoms after the shots didn't start until the next day, but when I got then I knew I was expelling the baby... Horrible pain cramping diherrhea and throwing up all at once. Went to e.r. It was so bad. Id never recommend those shots. Honestly my guess is your body didn't expell the baby yet. Hopefully this is all over for u soon I know how youre feeling.
Is it possible this could be a new pregnancy?
