Ladies answers needed please

Ok so I got what I thought was my period but it was really light and short and it lasted from may 1-may 4/5(morning it ended). And my so and I had sex on April 26 and I checked my tracker and it says I ovulated that day. So I've been going about my days doing my things. Well now I went to the restroom and I wiped and there was some light pinkish brownish spotting. I'm really confused. But I have to say I haven't been feeling well for the past few days. I took a test (may 3rd) just to get it out of the way and it was negative. So Idk what's going on. Am I pregnant? Or is my mind playing tricks with me.
