My last period was Sept 8-15th and my ovulation period was between Sept 17th-26. Ovulation Day Sept 22nd. Had sexual intercourse Sept 16th and sept 21st. My period is late by 9 days. I had very very light bleeding for 2 days and then nothing after that. Could I be pregnant or?

Also my period is irregular but this has never happened and my fertility and <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">period apps</a> are on point majority of the time.
