Hi, Thanks for using HCM.
Second time , that is in march, as you had intercourse in safer period, chances of pregnancy
As she is having brownish discharge now, it could be her regular period.
If she notices passing any tissue in blood or excess bleeding, then Get UPT test and blood HCG
Consult your doctor for examination and management.
Hope I answered your question. Feel free to ask me if you have any further queries.
Wish you good health. Take
