My last period came on the 28th of July, ended on the 2nd of August. I had sex with my partner last night, & after i had gotten up to go to the toilet i noticed i was bleeding when i whiped myself, I didn't think much of it but ive had cramping most of last night/early hours this morning & all day today, the bleeding stopped this morning & was a light brown colour! My period is due on the 25th of August, so in 9 days time. This has never happened before, does anyone know what this could be?
