I’m impatient...lol anybody else?

So my guy and I have been trying for a few months now. We did our thing like every other day during my fertile time. At least I think it was my fertile time. I’ve been off on calculating when AF will come. Sometimes I’m a few days off which makes me think I’m prego, then sometimes it comes a week early. Well about 3 or 4 DPO I started feeling super nauseated and got super sick from just 1 potato chip. Since that day my nausea has increased, I’ve become increasingly tired, my boobs are sore and feel a bit firm, everyone says I look tired but glowy, and lately like past few days I’ve been lightheaded. I’ve taken 2 home tests, one I took 6 DPO and the other today which is 12 DPO. Am I crazy and super super stressed out? Or is too early to tell? Lol ughhh I hate waiting and not knowing.
