Ovulation day

I had a natural miscarriage 23rd April. Test was negative by the 24th I bled for 4/5 days. I have been using opks but not everyday, the days I have used I've never got a positive, have missed about 5 days all in. According to glow i am due af in 6 days. We bedded on ovulation day (according to glow), is there a good chance I could be pregnant? Or would my cycle be thrown off due to mc
