Am I just crazy..? Ugh.

Okay so we've been ttc for 3+ years...i don't know if or when I ovulate but flow always has my period starting on the correct day.. So all last week during and before my fertile week my breast have been so sore... Then right after my fertile week and ovulation... I had mild cramps on the right side...felt like my period.. And now, I woke up and I spotted bright red/pink and that was only once... And I just have cramps still... My period isn't for another 10 days... What do you think? Period or could I be pregnant... Ugh im just hopeful. =(
