I have never done acupuncture but my husband has and it works every time! I would just talk to your doc and make sure it is ok then make sure you get connected with someone that is an extreme expert on acupuncture so you get the best results.
I cannot even profess to understand how it works or why it works but it certainly does. I know my husband pays about $50 to $80 per session and the last one he only needed one session. It was amazing.
I say if your doc says it is ok, then give it a try.
I am on child #4 and this pregnancy is the only one that I was debilitated with nausea and down for most of the day even with meds from the doc. Ultimately, apples and straight Coke (in small doses) is the only thing that worked. I am on month 6 now and still get sick but it has lightened up so there is light at the end of the tunnel. Hope you feel better, good luck!
