Welcome to ehealthforum,
If you have taken emergency contraceptive pill within 24-48 hours of unprotected intercourse, it should prevent pregnancy (provided you were not sexually active after taking it). Withdrawal bleeding occurs within 5-7 days of taking the pill indicating that it has worked (which may not occur if it is taken close to periods). Since these pills contain high dosages of hormones, these affect the hormonal and period pattern causing delay in your next periods. Wait and watch for your periods which could be delayed due to the emergency contraceptive use. Visit your doctor/gynecologist for further evaluation if periods do not start within 10 days or if you suspect chances of pregnancy, or if you develop any other new symptoms. If pregnancy gets ruled out, and if you are not ready for pregnancy, but intend to remain sexually active, you should consider visiting your gynecologist to get started on suitable regular birth control measures to be protected (after your periods). Be regular with birth control use as instructed. Avoid having unprotected sexual contact if you are not ready for pregnancy.
Hi. I am in the same situation. I am now 3 days late and took 4 different pregnancy tests all of which come out bold negative. I have no symptoms of pregnancy. I feel like my period is coming, got some acne, and lower back pain but still no period. I had used ellaone within three days of intercourse (which was a day after my period ended). I did it to protect myself just incase given that i knew I wouldn't be ovulating for the next week. I didn't get any withdrawal bleeding or anything. Could i be pregnant? I took a pregnancy test that detects HCG at 10 miu/ml however it also came out negative. Please advise. Should i wait for my period for another week or should i go and get a sonogram. They don't do pregnancy blood tests where I am currently living.
