Halo guys, am a Lil bit confused at the moment. My period for may and June started on the 1st to 6th. On the last day of my period June 6th I had a protected sex with my boyfriend, it's supposed to have come on the 3rd of July but am 4days late already, before now I noticed this whitish discharge on my panties, I carried out a urine test this morning and it's negative . I don't know if am getting the date all mixed up or is there something wrong somewhere?
