It's probably nothing, but I'll just check in case it's a symptom of something or other...
I'm 24 weeks, and keep having weird dizzy spells where I suddenly go all hot and dizzy and feel sick. Sometimes I can tell it's coming because my ears start feeling blocked up and my heart starts beating faster. Also my bump aches, like I've strained a muscle, but it doesn't feel like the braxton hicks I had with my first baby, unless they feel different with subsequent pregnancies?
Is there anything I can do? I'm getting loads of sleep and eating pretty much constantly.
