Thanks for the query.
The chance of pregnancy
is less, as you had intercourse in the first week of the menstrual cycle. During that period there is less possibility for ovulation in case of regular periods.
When you think of something that can come in our dreams.
And consistency of the stools can change depending on many factors. So you continue the tablets.
Any if you miss your expected date of periods just go for pregnancy test once to rule out the possibility.
