Advice please!

So I tried to convieve almost three weeks ago. I took pregnancy test but they all were negative. I was two days late for my period and came on for only 2 days and a little bit of spotting the third day. My af was very light this time Around and usually are between 4-5 days. Do you guys think I could be pregnant and maybe it's just to early to tell. Help please, anything would be nice. Thanks in advance 😘
