I had unprotected sex on the 27th of December was the 5th day of my period and had protected sex on the 28th of December and then took Postinor 2. I took the 2nd pill right after 12 hours. I got some bleeding on the 5th of January and it lasted for three days. Was that my period? I was supposed to get my period on the 21st of January and today is the 31st of January and I still didn't get my periods. I have an abdominal pain and cramp as if I will be getting my period but there is no sign of it yet. I have noticed some milky white stringy stuff coming from my vagina too. It smells weird. Am I pregnant?
