I Have Questions

So my hubby and I have been trying for baby #2 we just started this process so I’m definitely not getting my hopes up to get pregnant right away it took us 3 years before we even got our first baby but I’m a couple days past ovulation and I think im experiencing symptoms but I am just not sure. I am having breast tenderness, and some slight cramping and my sense of smell is crazy right now. I don’t know if it’s too soon to be experiencing anything or I just want this so bad I’m over thinking. Next week on Wednesday will be 6 days before my period and I plan to start testing then. I guess what I’m trying to ask is because I want this so bad am I actually having these symptoms or is it too soon. Also I’ve been super moody and soo tired like can’t keep my eyes open tired.
