Thanks for the query.
I understand your concern.
Little bit of irregularity in periods can occur due to many causes.
Usually menstrual cycle with length of 21 days to 35 days should be considered as normal only.
If you want to rule out the possibility of pregnancy and implantation bleeding, please go for urine pregnancy test once.
