Hi anyone reading this I'm Sarah πŸ™‹ I'm due my period tomorrow 17th march it can come a day or two before or after. I was spoting from Wednesday mostly clear with a bit of from tinge sorry tmi, then clear while i wiped last night and there was between light and dark red so i used tampon woke up today to clear discharge again I'm baffled i took a test Wednesday and yesterday both times in the afternoon and they were negative i had sex on my ovulation dates but towards the end 3 times. Any ideas ? this isn't like my usual period that is anyway πŸ˜ƒ
