i have had 6 miss carriges, and i am a little worried, i have slightly different symptoms from when i have been pregnant in the past. could i be pregnant? i have sore breasts, sometimes itchy aswell, constant heartburn , i am tired alot aswell. i am due for my period on 20th oct, but had a small bleed (just after id been for a wee when i wiped) 2 days ago.
