Implantation or AF please help!

I’m so confused with what’s going on I’m usually dry leading up to AF but I had watery stretchy discharge. AF was due yesterday I spotted through out the day which is unlike me usually I have an extremely heavy flow from start to finish. Is anyone else experiencing this? Feel like I’m loosing my mind I’ve got slight cramping and an awful headache. ( I’ve put the photos in order)
