Just need advice

My CM says I ovulated around the 2nd but my opk said I ovulated on the 5th...so I guess I am 5-7 dpo. I don't know what to trust. I know I need to wait to test, but I feel so nauseas this morning..and bloated, but not like period bloating. Plus I have been craving sweets nonstop only since yesterday. I have one daughter so I know early symptoms, but I don't know if I'm just on high alert for them right now or if I'm having early pregnancy symptoms! Advice?
