I'm feeling really low today, all my other symptoms have dissappeared and now i have AF symptoms really strong this morning (hav'nt got AF yet but know its coming). i just don't know how long i can keep doing thing. i just to cry. For the past few years i have been running a business and terrified to fall pregnant because i was just so busy...have I missed my chance? I just didn't think it would be this hard as I already have two children naturally.
