Welcome to healthcare magic,
I hope you are doing well.It is good to know that you took good precautionary measures after the unprotected sex.Prostinor 2
usually is quite safe except the nausea and vomiting
symptoms which are sometimes overwhelming.As far as lower abdominal pain
is considered it can be just vague/anxiety
or it could be because of the possible withdrawal bleeding.
If you miss the period you can consider doing the urine pregnancy
test home kit(the possibility of you needing this is also quite remote).I hope your queries have been answered satisfactorily,if any doubts you can still buzz me.
Have a healthy life
