Is it normal?

I've been having bad cramps all day and feeling sick I'm not due on for another 9 days and I've never felt this bad especially so far from when my period is due its usually a day or two before but I've been wiping and theres been a little pink mark on the tissue, I havent been able to eat as i feel to sick nor drink, has anybody felt like this. Do you think it's because I'm stressed about TTC to much as weve been trying for a year and a half this month.
