Short cycle or af late?

Bethany

Had a miscarriage Aug 6. Period came Sept 9th which was pretty heavy and lasted 5 days with a day of spotting. I'm pretty sure confirmed ovulation on Sept 30th with a positive opk on the 29th and bbt increase the next couple days. On 6po I had pink/brown spotting throughout the day when I wiped. woke up the next morning with dark brown blood on pad not alot tho just a couple spots. Then had some bright red blood with tiny clots when I wiped, never on pad mixed with brown spotting for the next couple of days, so the spotting lasted 4 days. Period was suppose to start 10/14 and negative pregnancy test that morning. I'm now 16dpo and 2 days late according to all three of my apps. Neg pregnancy tests. My periods are irregular but usually have 30-35 day cycles. Should I count that as just a weird period or wait and see if AF will show late?? No idea if my body is out of wack since miscarriage but I know no period means no baby and I just want to try again if this wasn't my month.
