Okay, 3rd time having strange discharge implantation?

1st and second picture side by side. First few times it was like a slimy mucus discharge then now it’s like water and the brownish color. I feel awful. I’m having the strangest twinges and cramps and shooting pains and BACK ACHES galore. It’s getting where it’s making me feel irritable and nauseated. I don’t feel really sick but no kind of food sounds good I have to force it down. I did have sex when I ovulated.

It’s obviously lighter too. This bottom pic was the second time and the top pic up there was just now ( 3rd time ) I’m also having acute coochie cramps and butthole cramps. Like everything hurts... not sever but it’s so annoying.
