High lft in pregnancy. Effect to foetus?

Currently 30 plus 2 weeks pregnant. I got lft done at 26 th week and the values were sgot - 69 , sgpt - 129 , Alkaline phosphate - 154.. but no itching was there, so my gynae didnt suggest any medicines and said its normal to have slightly elevated enzymes and to repeat lft after 4 weeks. Now in 30 th week the values got raised further , sgot - 111 , sgpt - 171, alkaline phosphate is 182. But now very mild itching once in 2-3 days. Still my gynae has refused to give any medicine and suggested me to stop proluton depot injection which i was taking weekly due to past history of incompetent cervix as according to her, proluton depot can also raise liver enzymes and told me to repeat lft after 2 weeks now.. can delaying the treatment cause any effect to foetus? As this is my rainbow baby .
