...asking because I'm 9 DPO and I have been feeling so nauseas...wondering if it just anxiety..but I would like to know if any of you ladies who are or have been pregnant felt any symptoms within a week after conception. 
**Took a test...big fat negative...I am supposed to get my period in about 4-5 days.
