Reply to Nurse Annie's Post: thank you so much, can I ask one more question? How soon could you poosible feel s/s of pregnancy after conception. my period is not due til next week but I swear i am feeling the same things i felt when i was pregnant with my last baby, headaches, dizzy/foggy. i went to the md last time and they said i had the flu but i was in fact pregnant, could i be pregnant again
