Other points of view needed on pregnancy scare

[tankgirledward.livejournal.com]

One of my best friends is super paranoid that she is pregnant and it is starting to get on my nerves. She went from thanksgiving break to the end of march without a period and during that time she had unprotected sex ONCE but no one came. She has taken a magic pee wand test about once a week for the last two months and they have all been neg. The week before she went to her doc to have her blood work done for her thyroid she had them do a pee test and it came up neg too. She says that her last period was strange. It started out dark dead blood for about a week and then ramped up to monsoon season with extra big clots for a week. She has also lately been complaining of pressure in her abdomen(she's sure it's a baby) and being very gassy/burpy. She also says her breasts hurt but aren’t tender (WTF) and she is getting a milky discharge when she squeezes her nipples. She has NEVER been regular. She took BC pills for about 6-8 months and stopped that i want to say in july/augest. She is afraid that her thyroid replacement is messing with the test accuracy. I think that the stress of finals is getting to her and her thyroid replacement/coming off her BC is messing with her hormones. Can I get a second opinion?
