Thank you for your query. I can understand your concerns.Irregular periods
with brownish discharge occurs on taking pills irregularly. It will resolve by next cycle.
But still to confirm it i want you to do a pregnancy
test with a UPT kit . It costs cheap and is available in all pharmacy. The instructions on how to use it & how to read the test is given on the Kit Box
Feel free to consult me directly
