Had a similar thing happen to me about 7 weeks ago

The pharmacit said to use any EBM I had first and keep pumping to keep my supply up. He told me to try and avoid bf for 24hrs post the MAP if possible. The MAP can really drop your milk supply so keep pumping and/or feeding often and I also took fenungreek and we didnt have too many problems getting back to bf.

I would speak to your pharmacist as they have better info on bf and medications than a lot of gps's and you dont need a script for it.

(Im still waiting for af after our accident but its been 7 weeks since our accident and have done 2 hpt's with fmu both were bfn's this week I just hate being so irregular with a while I'm bf)

good luck
