Dreaded postpartum period

I gave birth March 2nd and got what I’m assuming was my first period April 25th exactly 7 weeks pp. A week after it ended I spotted for about 4 days. Nothing since. Is this normal?? I did take a pregnancy test when I technically would have been 3 days late and it was very much negative. Please help put my mind at ease that this is normal and I'm not pregnant already🙃
