Hey lybrate-user,
thank you for choosing Lybrate.
As per your history, the sex you had on 7th was completely safe. So there are very less chance of you being pregnant on that day.
But the point of concern is 13th march .which lies on 11th day of your cycle which is assumed to be the close to ovulation phase of your cycle, and that could lead to preganancy.
Elaine? What is it? I haven't heard of this drug before or have you misspelled it?
I would suggest you to consult me privately so that I can guide you better.
Thank you!
