Late Period

Jennifer

I am 2 days late for my cycle. I was supposed to start on the 8th but nothing! My last cycle was on May 13-18 with having sex on 25 and my ovulation day on the 26 and also having sex that day as well. And again on the 30th. All pregnancy test come back negative. I have never been last on my cycle. I miscarriaged on April 19 and bleed for 6 days like a normal period. Could the miscarriage mess my cycle up.!
