Thanks for the query.
As you are on minera there is less possibility for pregnancy
Minera can cause side effects like amenorrhea
, irregular spotting etc.
Brown discharge can be due to collected blood from the endometrium.
Usually this will subside soon.
If you had doubt regarding pregnancy, once go for blood test
Blood test gives more accurate result compared with urine test.
If the test comes negative, no need to worry.
Consult gynecologist and take tablets to control the spotting.
Then you can continue with Minera.
