Hi there!

My period is now a day late and for a few days I've been having really heavy discharge both watery and creamy (sorry tmi), my cervix is high and normally around my period it comes down really low but I'm having cramps both in my back and lower stomach like when af shows her ugly head 😂

we had sex on the 20/8 which is the only time within that cycle and on eve is after my ovulation days but I don't think I ovulated when eve says I did as I was having my usual symptoms a few days before intercourse. I took a test this morning and while no pink line showed up there was a dented line where I think the line would of showed up so I'm not sure if this is a sign that in a few days I could get a bfp or if it's game over this time? What do you guys think? Sorry for the long post, it's my first time posting and I'm very confused!
