pregnant again? real symptoms or in my head?

Katie
I'm 6.5 mo pp and I still haven't gotten an official period yet. Hubby and I BD on 10/15 and 10-17. I had a LITTLE bit of spotting on 10/20. Since then I've been very emotional, lightheaded and nauseous at times, somewhat more hungry, and my belly looks a little bloated even though I lost 2lbs. Since I haven't gotten a post pardum period I have no way of knowing if/when I ovulated. I'm trying to wait until tomorrow or Monday to test since that would be 2 weeks since we BD. I remember feeling like I wasn't sure if my symptoms were real or in my head for the first baby because I wanted to be pregnant so bad. Does anyone else feel like this? Fingers crossed for BFP
