Hi,
Welcome to Healthcaremagic.com.
I had gone through your question I can understand your concern about your pregnancy.

It depends upon your period duration. As per your history, your fixed date of next period was 18th, that means if you had 28 days periods the ovulation date is 4th (14th day of your periods. It takes some time to get an egg to fallopian tube so 4th is not possible not is the 2nd because it was prior to 4th.
Now there are two more dates both of them can be the date of pregnancy because on the 5th day if some sperm gets penetration into egg ans succeed to fertilize the egg, so can lead to pregnancy. Last one is 8th date, it can also be because if the egg was not fertilized on 5th it takes 3-4 days an egg to become non viable for pregnancy so 8th comes between the rage or in range.

So it is either 8th or 5th, you can use same logic to calculate the ovulation period if it is not of 28 days.

Hope you got my answer, also provide your helpful feedback
Regards
