symptoms already?

So my fertile week started the 7th and my peak day was 2-3 days after I think. I'm currently on my TWW. Oh and I took clomid as well to help ovulation along. I swear I'm having some strange symptoms I don't normally have. Like I've been craving cheese for two days and today I have acid reflux and nausea all day - and I ran out of cheese so I'm not happy about that.
