Congratulations! That's is great news. When I found out I was pregant I too was excited and very scared. My ob gyn didn't have a clue about
lyme, but he was very through as an ob gyn. My lyme dr gave me amoxicillin throughout and my ob had no problem with that. So, he didn't treat me or my lyme at all but I continued with my lyme dr. The good news is that my daughter is now 2 1/2 and perfectly healthy and so smart. I was extremely sick with my pregnancy so taking anything (even water) most days was not even an option. I didn't continue on after and did breatfeed for 3 months. I am not sure even how much amox got into my system because my morning sickness was so extreme that I couldn't eat or keep anything down for the entire pregnancy.
I would try to find a dr that can get you the amoxicillin. If you want to breatfeed after they will recommend staying on it then as well so you will need a good year's worth. You don't necessarily need another ob but one that will work in conjuction with another dr. I also had my daughter tested at birth and again at 6 months and 1 year just to be certain. My lyme dr ordered the test at birth and her pedi ordered the rest as I told him about my chronic lyme.
Good luck. I am actually trying again after a miscarriage this summer for another. I hope to have some good news in the coming weeks as well. It is well worth all of it. Nothing better!
