Sysron N and Pregnancy

[Pinkarpi]

I had unprotected sex with my boyfriend on 6th Oct. He followed pull off method. My period was due to 16th/17th Oct (as my cycle starts 3-4 days earlier than last month). In the meanwhile I started taking Sysron n 5 mg thrice daily from 15th to 22nd Oct. Then I stopped. I took 100 mg Sysron N in total during that time. I stopped taking Sysron after 22 Oct. But my period yet not started and I started feeling nausea n pain in lower abdomen. And I am also feeling very weakness. Now my concern is that wheather I got already pregnant or not. And 2nd thing that I took 100 mg Sysron N for 7 days (from 15th to 22 Oct), will it create any adverse affects on foetus.
