AF 4 days late and I feel 'not right'...

I've felt really not 'right' for a week now

- fatigue

- sporadically feeling sick (although no actual vomiting)

- intense shortness of breath

- lightheaded & dizzy

Almost fainted this morning on my way into the office, thinking maybe it was low blood sugar levels or something, had a sugary drink and something to eat and almost four hours later, I still don't feel right.

TTC for 5/6 months, putting off testing for as long as possible to avoid the standard disappointment.

Anyone else in (or been in) a similar situation?
