Take home test 1: faint negative
Blood test from doctor 2 days later: negative
She has a very light period.
She then started getting nausious alot and had to eat saltines and only certain foods. Her breasts grew a size and are extremely sore to the touch. Her lower belly got so big that she had to use rubberbands to keep the pants together. Naturally, I got concerned and, along with a co-worker of hers, we were totally convinced she was pregnant.
Week 2 (a month and a week since possible conception):
Take home test: faint negative
Blood test from Doctor: negative.
Since then her belly shrunk and she can now fit back into jeans. Relieved husband-to-be but depressed fiance (she really wanted it badly). Moral of the story: Don't count your symptoms until they're proven?
