if you have regular periods and you are not sure of ovulation you should take a opk, to see if you are ovulating, and if you wish to avoid it! then thats what you should do, and as you used protection you have a low chance, but a chance is still there, if you miss your period next month, take a test.
Just to add, i have some pain on lower right side and last night had pain under and below my right breast. This morning a dizzy head and ear pressure.....Help please!
You used protection so that lower chances of becoming pregnant anyway. What you're feeling is not due to pregnancy. All you can do is wait until your next period is due and if it doesn't show on time then take a pregnancy test with first morning urine. Most likely you won't become pregnant from using protection though.
