I'm 18, with no kids! My boyfriend has no kids as well he's 21. We own our own house 4bd 3 bath on 8 acres perfect home for a family. He doesn't really want kids right now. Today I was curious and took 4 pregnancy tests and 3 came out positive but one came out negative and it was a different brand! I also was diagnosed with PCOS just a few weeks ago! I go in next week for an ultrasound on my ovaries & also blood work! What should I do?! How do I tell my boyfriend ???
