Advice needed

I'm ttc #1, on jan 1, I took a pregnancy test and got BFP on CD 35. I was so excited, however on jan 7 I had an early miscarriage from what I'm getting from this forum a chemical pregnancy. I should've have gotten a period on 3/15 or 3/16 so I'm about 3 days late (cd 37) Took a test this afternoon and it was negative. I'm just wondering if it's possible that this time around my BFP will come later than last time? My cycles average 31 days but the longest was 35. The symptoms I have a slight headaches, slight breast tenderness, and some nausea, and slight pressure by the vagina area, nothing like my period cramps though. Usually my af cramps come about 2 days before af, so far nothing. Just wondering if anyone has gone through the same thing. Hopefully I made sense in writing this.
