Advice needed

Hey everyone! I’m 6DPO and due for AF in 8 days I’ve been very nauseous. I’m trying not to get my hopes up because my boyfriend and I have been trying for the past 3 months but I don’t ever get nausea before my period. I’m just feeling very out of sorts and I’m hoping it’s not just all in my head. I also don’t know if I ovulated this month, I usually get pains but this time I didn’t and the OPKs that I bought were all faulty (I guess store brand isn’t always good 🥴) I know it’s way too early to test but any other advice and words of encouragement would be great!
