Bleeding?

Hey ladies! I last had my period November 6-10 which I was 11 days late on. My husband and I want a baby so had sex on November 11, 12 and 21 and he came in me on the 12 and 21. My eve app says I’m fertile (I’m new to this as pop so I just logged my last period and it gave me dates. I’ve been more active on another app called period tracker in which that app says o I m not fertile till the beginning of December. I’m not sure why I could be bleeding? What do you guys think? I just ended my period like 2 weeks ago and my average cycle is like 40 something days long...? What do you guys think? The bleeding started tonight randomly. I took a pregnancy test Tuesday morning and it was negative...
