Is TTC making me lose my mind?! Idk what to think anymore!

Chrissy

So I had blinking smiley face on my clear blue advanced for 7 days now so strange!! I also use strips and had 3 positive opk's in the last 7 days. I'm cramping so bad right now almost feels like Af but she isn't due until the 31st. Slept all day yesterday literally.. Nauseous today .. am I losing my mind? Is this what ttc does to u?
