Hi,
My Girlfriend's period started on 11th aug 2013. It ended on 15th aug 2013. On 16th night we just had foreplay. We wore worried about the pre-come, nothing else, we didn't have sex, neither I ejaculated. On 17th evening she took Ipill ( she also took I pill around 2 months back). Her periods were due for 9th sept 2013 and its 17th today. She gets some symptoms like stomach pain but with no periods. We even did home pregnancy test 3-4 times all came negative .
Please guide.
