9dpo and odd symtoms

I'm 9dpo and I've been having some strange symptoms 2 day ago I started with light cramps period like and also bloating light-headedness everytime I move and I'm exhausted just going up the stairs I thought I was dehydrated but my pee is clear. I've had soup and water today and I have a headache. I suffer from ibs and had terrible diahhera with no cause really I usually get constipation and sulfur burps last night and a little this morning. It is possible I could be pregnant? as me and my husband were at it on my ovulation day with EWMC. I've also had really odd dreams.
