hi good day! Is it ok that i used as an alternative the Althea pills? i believe that i am fertile when we do the thing . i took two pills last night around 10pm. it was 18 hours after unprotected sex and then i took another two this morning 10 am.. am i doing the right thing? will i continue to take the remaining pills by twos until i finished all the pills ? or should i take it 3x a day until all pills are consumed.
