My husband and I have been trying for our second baby for around 6 months now but had no joy. I'm due on in 4/5 days and the last few days I have been so exhausted that I've been going to bed 2 hours earlier than normal and I've also felt very sick to the point I've turned away certain foods, not felt like eating. Also (sorry for details) but when my cat messes in her litter tray and while changing my little boys dirty nappies, I feel like I'm going to be sick and sort of feel like I have heightened sense of smell as normally this wouldn't bother me. I've taken a cheap eBay ultra sensitive test but its come back negative. What do people think?
