Hello and welcome to HCM,Pregnancy
can be confirmed by urine pregnancy test.
If conception does take place, the next menstrual cycle does not occur.
The chances of conception are high during ovulation but it is not 100%.
As you have mentioned that bleeding/ spotting started on 9th, this date is within one month of the last menstrual cycle.
The appearance of menstrual cycle rules out pregnancy but to be doubly sure, get the pregnancy test done to confirm.
Thanks and take care
