Desperate for an advice

Hi everyone , I'm a bit concerned, just took a pregnancy test and it was negative , premon and glow apps says I'm 2 days late ... The reason I'm worried it's because my ovu seems too close to my period ( i use opk'S to track it) and my lutheal phase so long , it may b a problem to conceive ? ... This never happened to me , i had a miscarriage back in may .. could it b the reason my cycles are so messed up ?? Is there someone dealing with the same ? I'd appreciate any advice , I'm really desperate don't know what should I do ....I'm so lost 😔😭
