Super early miscarriage

So I had a miscarriage/ chemical pregnancy (I was about 6/7 weeks a week of positive test followed by cramps and bleeding) back in March. I was going through a rough mental time and the man who would be the dad and I are best friends but not in a relationship we were living on opposite sides of the country at the time and I kinda just ignored the situation. I didn’t tell him I got positive tests because I wanted to wait and see a Dr to make sure but by the time that came it was over. It never bothered me or really processed what that all meant but now it’s randomly the only thing on my mind. Him and I are still best friends and living on the same coast now. But I haven’t told anyone about this. Not sure why it’s bothering me now. Anyone experience delayed reaction or emotions to something like this.
