Is it normal to experience spotting while on norethisterone?

Mid cycle spotting is not uncommon, and it occurs around the time of the ovulation, due to a temporary drop in the levels of hormones (which helps to build up the inner lining of the womb). If you have taken the birth control pill and it stops the mid cycle spotting, it indicates ovulation as the likely reason for the mid cycle bleeding. This is because the birth control pill works by inhibiting ovulation (hence preventing pregnancy). Usually mid cycle spotting due to ovulation lasts 1-2 days and clears quickly.

Norethisterone is a type of progesterone hormone pill that can be used for various reasons, eg heavy periods, delaying periods etc. However, it is important to note that Norethisterone is NOT a contraceptive pill. Meaning, it does not provide you with birth control effects. Hence, to answer your question simply, the answer is yes, there is a chance you may get pregnant if you are taking this medication and having unprotected intercourse without additional contraception.
