Stopping progesterone cold turkey.

hi

i just got my bfp. I’ve been on progesterone suppositories since 3dpo (I’m now 14doo).my progesterone level was fine but I had a chemical last month so they decided to put me on it just in case. I spoke to them this morning (they confirmed my bfp beta) and they told me I don’t need to take the progesterone as my level was fine and to stop it. I’m concerned this may harm the baby stopping cold turkey should I push it with them?
