Going crazy

Been testing for a couple days and getting positives on a night and negatives on a morning and sometimes can be other way around I did bleed for a tiny bit other day when I was 7days until my next cycle and my cervix was also love soft and open since I was fertile why could this be use ally it's high and super closed as partner says straight after fertility finishes I did Nd ovulation test at one point with pregnancy tests to see if it would come up baring in mind I ovulated a week before and come up with a strong line like I was fertile while pregnancy strips are sometimes saying I am too so I'm a little confused  sorry if you can't read this right I'm tired and very much confused
