<s>[INST] Hey, I am 16 weeks pregnant and I was prescribed Duphaston since I found out that I was pregnant due to PCOS prior to pregnancy. The dose I am on is 2 tablets of 10mg a day. I just realized that I have forgotten to take my morning tablet. What shall I do? Shall I take two tablets or just forget about the missed dose? Will it have any negative effect on my pregnancy or baby?  Thanks :) [/INST] Hi, Thanks for the query. I understand your query. Phaeton is given in early pregnancy.to protect it by supplementing progesterone hormone (present in phaeton) Usually it is continued till 4 months of pregnancy... for by this time natural progesterone start secreting.  Progesterone like all other hormones . Must be taken at prescribed time ( here twice a day . That is 12 hourly) You had missed a dose... it should have been taken the moment you remembered about missing dose... You should not take double dose at a time... continue it as usual. Take care not to forget it again. Continue till your treating doctor advises discontinuing. Have regular monthly check up.  Thanks. </s>
