EMERGENCY!! Please respond ! The more opinions the better !!

Okay so me and my boyfriend has sex April 9th and it's about to be 2 weeks the 22nd of April. I had sex the (9th) which was 3 days after my period ended. On <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a>, it shows that I ovulated 2 days ago but my fertile window wasn't 2 days ago. I took a pregnancy test and it was negative but it was before 2 weeks which was the (19th of April). I had sex 2 days after <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> said in Notifications that I ovulated and he came inside me. Does that mean there's a chance of pregnancy ? I've been also feeling light headed and dizzy, serve cramping, and some what I feel my breast a little larger than they are normally. I need your honest opinions !! It can really help !!
