My periods are late. I had unprotected sex but I took I pills within 8-12 hours after sex. After 3 weeks, I saw few brown spots and thought it was my period but for 2 days it was just the spots and nothing else. On 3rd day ,there was no spot so I took Norlut N for 2 days .Meanwhile, I also took
pregnancy test but the result was negative. For 1 week I waited for my periods but it didn't come so, I again took Norlut N for 2 days. It's been 3 days now but I see no sign of periods. What should I do?
