Pregnancy and Tests

Christa • Loving life with my little family and the adventures we take! Might give my toddler a sibling in the future but not 100% sure 🤷🏼‍♀️

Has anyone ever been pregnant but had both negative home and blood tests? I've got a friend who has all the pregnancy symptoms and has had family tell her they dreamt she was pregnant and all recently but all her tests came back negative.. she has the sore boobs, nausea, little vomiting, food cravings, foods aversions, excessive fatigue.. She had like a week after her period but not sure if that was her exact ovulation date or not.. but then about 3 weeks after the fact she's got pregnancy symptoms and then her period was only spotting 2 1/2 days and was really light pink which isn't normal for her. That was julys period. According to her calculations based on lmp she should be around 9 weeks but still getting negative tests. Could she be pregnant and it's just not showing on the tests or is there something that would cause it to seem like she is and her go thru all the symptoms?

Just trying to get her some help in anyway I can.. she doesn't wanna see a doctor again cause that the last time she did the nurse told her she was crazy and asked her what drugs she was on cause she had no reason to feel the way she did.. my friend doesn't do any kind of drugs tho.
