"Ugh, girls, how do I know when the plug is coming out if I take more Utrogestan? Yesterday for half a day and yesterday for half an evening it was pulling down my belly, in the evening as always I put the candle, and this morning I went to the toilet and on paper I noticed mucus of milk color, almost white, not a clot, like in internet pictures, but just like phlegm ? Not much, not little, now I think about discharge from Utrogestan or the plug?!" ???‍♀️??‍♀️
