It hurts not to be pregnant

The past 2 weeks I have been charting my bbt, reading forum pages, feeling like I am pregnant because of the symptoms I have. Tired, lower stomach pain, nausea, gas, dizziness, tender breasts. I I had a late ovulation and an implantation deep at 8dpo and my temp was really good too. Tested negative on 13 dpo but I was so confident at this time that I was 98% sure I was going to get a BFP soon. Silly me, I started spotting this morning at 15 dpo. It hurts so bad that I'm not pregnant. The last days I spent planing for a future I could be pregnant but I think I have to stop fooling myself too. It just really hurts ?
