are these good signs??

Lauren
I ovulated approx 8 days ago and I'm due on next Thursday. For just under a week I've had really sore breasts, really bloated and 2 days ago I kept getting a really sharp pain which felt like it was on the right hand side of my uterus. 
I did an Clear Blue early detection pregnancy test yesterday which was negative (silly idea as it was still too early to test). Could these be positive signs? Really hoping af doesn't arrive next week! 
Today I feel nauseous but I'm wondering whether these are just early signs of af. 
Any advice would be appreciated! Came off the pill 5 months ago but would say we've been actively trying for 3 (ovulation tests etc.)
