Sigh...

Is it too early to test. Af is due in 4 days and last month my period was literally only a day or 2 and was super light. Lately ive been super moody, hella hungry like no matter how much i eat i cant satisfy my hunger, ive been feeling like ive had to puke at all times of the day and the smells of things i love like koolaid and pizza and even my husbands cologne repulse me. We have been ttc for about 6 months or so, would it be too early to test if theres a little spawn making me feel crazy or do you guys think its all in my head. Im just not ready for a bfn because my husband has been asking for a baby and my son wants a little brother haha
