Ttc baby # 1

So I am trying to conceive for baby number one and I am 12dpo today. This morning I woke up feeling extremely tired I just got up for the day around 1245pm. That's not like me at all. Yesterday I was feeling nauseous on and off throughout the day with minor headaches which I would take tylenol for. I drink my premama drink mix everyday day and the premama prenatal vitamin. I believe I only have about 3 maybe 4 drink mixes left and I'm curious if I should test. I have been doing very good with not testing or thinking about it since there are new things going on in my life distracting me. I usually have a lot of water cm before af but I don't this time or atleast not yet. I purchased another bottle of drink mix for next month figuring I would need it...but I'm getting very antsy to know if I should test. I have all the normal symptoms except for increased sense if smell...
