I had unprotected sex with my boyfriend from Jan 16th to Jan 23 and used VCF foam once.. I noticed on Jan 18 a brownish color on the toilet paper then a mucous with a little bit of small spots of blood on it.. I thought maybe it was from the foam irriating my vagina but now I am wondering could this be a sign of pregnancy?? I am still seeing a very slight pink discoloration. I am not even sure we waited the alloted 10 minutes for the foam to start working?? HELP!!!!
