Yesterday I had a few small symptoms, and it took me a bit to piece them together that that's what they were.
The first that I realized what it was was visual effect? distortion? Sort of like when you see those shiny circles in a photo that's looking into the sun? I was having a conversation with someone and just couldn't see half their face because this shiny/glittery thing was making me blink. I couldn't figure out why it was hard to see when I figured out there was this distortion. I remember having something similar during the first time around.
The other was headache.
And the last was faintness/dizziness. I felt weak, and then that flushed pre-fainting feeling as I was hurrying home (late) from work last night. I wanted to see my kiddo and was late and rushing and then after a couple of blocks realized that I had better slow to a walk if I wanted to make it home without assistance (since I nearly passed out and had to sit down early in pregnancy the first time).
None of those were any fun, but they made me feel a bit better that the embryo is continuing to grow and suck my resources. :)
