There is no harm if you have sex when on Krimson 35
Krimson35 is an oral contraceptive
pill. It is used to prevent pregnancy
. So if you have sex when you are taking these, you wont conceive provided you are taking these regularly on fixed time.
However even if you conceive when on these tablets due to improper usage, there is no harm to the baby caused by their intake.
I hope I have answered you.
