So it’s had spotting instead of a period for two days and today was the third it’s been mostly light and no pains, my usual period is heavy for the first 3 days, this morning i tested as I had a feeling and also because i have my second jab appointment and two lines came up the first line is slightly faint but very visible and the second line is very dark. Do u think this is a positive ? I started spotting the day my period was due and this is the third day .
