I had sex with my husband on 29th of august and my periods had ended on 27th of august. my husband used a protection. at the end we confirmed it was not broken. For safer side I even took an i-pill. I had to get my periods on 17th of September, today's is 25th of September and still I have not go periods. I'm having colourless n odourless watery discharge daily. is this a side effect of i-pill? Please help.
