Symptoms?

Not sure if this is the right place. I think I had implantation bleeding yesterday. Today I woke up and almost threw up, went through the whole day feeling like throwing up. Came home and ate dinner and now I feel so full and like (tmi) throw up is in my throat?  Along with feeling like I've had a cold for a week now and waking up early morning craving chikfila. Also since about a week after sex I have been so exhausted I have been taking naps and then sleeping through the night earlier than usual and having trouble staying awake throughout the day. I know it doesn't make sense to have symptoms before implantation but I don't know? I never eat in the morning because it makes my stomach upset but lately  I've craved chikfila in the mornings. No idea what's going on.
