LO is almost 6 months old, and for the last week or so I've been having some really icky nausea/dizzy spells. It's mostly been at night when I'm going to bed, but the last couple days it's been more frequent, like I just got really nauseous after lunch. I took a hpt just now but it was negative, which makes sense--dh and I are using condoms so it's not likely that I would be pregnant anyway. In the past I've also had problems with nausea related to anxiety/stress, and I am a little stressed about lo starting daycare next week and me going back to work, but nowhere near as stressed as I have been in the past when I had these issues. I'm wondering if this could be my body gearing up for a period again?

Did anyone else have any kind of nausea issues with their first period postpartum? Or other fun PMS symptoms for me to look forward to?
