I lost my virginty and now I'm worried

I lost my virginty on Friday the 1st (we used a condom) and I got some spotting after which I thought was my period cause it was due in 2 days. I'm still bleeding slightly but it's definitely not my period. I did some internet research and now I'm really worried I'm pregnant! SOS!!!!!

Update-

My period is 5 days late so I took a pregnancy test and it came up negative! Crisis averted
