Thanks for using HCM
Your previous period was prolonged, could be due to operation stress, nothing to worry.
Ovulation kit is basically to detect fertile period, not pregnancy
, two lines shows hormonal
surge in your body.
You can get one UPT done check for pregnancy.
Your loose stool
could be due to food infection, cramps in pelvic region due to increased bowel movements. which is common in diarrhea
Hope i have answered your query, have a good health
