Hello doctor, maine or meri girlfriend ne 8 november or 9 november ko sex kiya tha jiske bad mein usne 9 november ko 2 I pill tablet use ki thi. Uske baad humne 24 (after 4 pm), 25 (2-3 time) & 26 (before 8 am only for 1 time) november ko fir se sex kiya tha or usne ek I pill tablet use ki thi uska last period 2 november ko aaya tha abhi tak uska period nhi aaya hai to kya karna chahiye. Her last period was started on 2nd november & ended on 4th november. So have I worry too early or not because I read in some websites that I pill can cause delayed period.
