<s>[INST] I have been using NuvaRing for almost a year now and my period has been coming the same day i take the ring out, My boyfriend and I had sex, last month, while i was on my period and didn t have the NuvaRing in, he ejaculated in me. I was expecting my period on Friday or Saturday and it is now Monday and no spotting or bleeding [/INST] Hello thanks for the query. Having unprotected intercourse while your period is going on, results in very low chances of pregnancy. Also, how long ago did you remove the Nearing ? It is normal for the menstrual pattern to be altered a bit after removing or inserting the Nearing, as it is a hormonal contraceptive. So, please wait for a week or two, and if you still do not have a period, please go for a home (urine) Chat Doctor pregnancy test. If that is negative, consult your doctor to find out the cause of absent periods. Please switch over to any preferred method of contraception again, if you do not desire a pregnancy. Take care. </s>
