Aww I understand lah, that waiting feeling is so stressful! A few of us mums have been there, sometimes our body hormones just go haywire and delay things without being pregnant, especially if stressed or ada changes in routine. Clearblue Digital is pretty reliable though, so if it says not pregnant likely you're not, but if your period still doesn't come in a few more days or you're really worried, might be worth checking with your doc just to rule everything out and see what's causing the delay. Hang in there, hormones can be so confusing!
