I was involved in sexual activity on 16th Jan which was my 5th day of my period. I took an ipill after 26 hrs. On 24th Jan I had bleeding which lasted for 4 days. After that I have been involved in sexual activity which did not involve penetration. My last period date was 12 Jan. Since then I haven't had my periods. I took a urine
pregnancy test on 27th Feb which was negative. Please tell if I should be worried about pregnancy. Please suggest me what steps should I take further.
