Should I talk to my assistant manager or tell my boss?

So I've been having very strong pregnancy symptoms and yes the tests and the blood one all said negative. But I'm still having strong symptoms to the point my OB told me to come back because my results was considered a gray area. So it's not 100% and it's even possible ( rare ) for some women can fail the tests and still be pregnant. It's possible that I could be like those other women. Just today at the day care center I volunteer at she was telling me she was 18 weeks pregnant when she found out she was actually pregnant after doing a ultrasound because she was also going through the symptoms and it did say she wasn't pregnant. So assistant manager was very rude in a way saying how I wasn't pregnant and it's all mental. Like I'm not going to throw up on foods I love and wanting to throw up just by smelling coffee craving foods I hate. she keeps saying how it doesn't sound like pregnancy when I dip pickles in peanut butter. Like everyone is different? But I don't know I just felt really uncomfortable how she was so determined to say I wasn't pregnant just because the blood and urine test said I was negative I mean obviously something is wrong if my OB said it herself to come back and re do it because it's a chance it could be wrong. She even talked about my OB almost calling her stupid and to find another one.
