If you have regular 28-30 day cycles then you are just around the ovulation period. You cannot expect a protection in this cycle with your pills unless you had used some other form of contraception
, as you started them late. Yet, it could be a simple ovulation pain. You may take some antispasmodic for relief. If you continue to feel the pain, contact your doctor. Nothing can be said about your pregnancy
right now until the onset of your next period, or to make it earlier, you can have a serum test for beta-hCG
levels one week prior to the expected date of your next cycle. Good luck.
