I’m 8 days DPO and I have been super nauseous the passed few days and have felt exhausted since yesterday. I’ve also been super moody since yesterday(crying for no reason then laughing out of nowhere). AF is due in 6 days. But usually I just have cramps and sore boobs. My boobs don’t hurt but my nipples were super sensitive yesterday. Also been having to pee a lot lately. Could these be pregnancy symptoms or just PMS?
