Me and my fiancé were enjoying our intimate moment one evening.There was no vaginal intercourse. He just fingered my vagina and had cm on my belly.Healso rubbed his penis against my organ but there was no penetration.We were worried about the pre-ejaculatory fluid, if by any chance during fingering , some fluid entered in. To be on the safe side, I took idoz 72 between first and second hour of this. All this happened on 19th March 8 pm which was 9 days following my previous cycle.I had my previous period on 11th March. My usual cycle starts on every 28th day. I had slight bleeding for an hour on April 11th which just looked like my regular flow in colour and consistency.but I didn't had my regular three day flow till now. What does this mean? Am I safe? Please help me out.
