miscarriage

Please someone help me understand 💔. I found out about two weeks ago I was pregnant, done three positive tests. Clear blue said 1-2 weeks, which would have been 4. I did another one on Wednesday just gone because I just didn't feel convinced, that again was another strong positive. I started to bleed early Friday morning. Went to the epu to be told all my test were negative, and to wait for my first cycle to try again. I didn't have a scan just urine and blood test. I feel so confused and broken cos I know I was pregnant but I've been made to feel like I made the whole thing up.
