Brief Answer:
Pregnancy at 50 years age is a possibility and you need to be aware

Detailed Answer:
Hi XXXX,
Thanks for writing in to us.

I have read through your query in detail.
Please find my observations below.

1. If you had your last periods on March 20 2015 then you might still be in your perimenopausal period.

2. There are women who have had pregnancy after having sex at 50 years age and it is normal but less frequent.

3. Since you had unprotected sex on April 4 therefore there is a chance of a pregnancy.

4. Please do a home pregnancy test at least 15 days following the sexual intercourse for accurate results. You can do the test on any day after 19 April 2015, if your period does not start by then.

Hope this answers your question. Please feel free to correct any oversight in my interpretation of your problems and discuss them in detail as per your requirements.

Hope your query is answered.
Do write back if you have any doubts.

Regards,
Dr.Vivek

Brief Answer:
Probability persists as you were fertile on 7 April 2015

Detailed Answer:
Hi XXXX,
Thanks for writing back with an update.

1. Since your last period was 20 March 2015, considering that you have a period of length 31 days, then you were likely to be most fertile from 3 April 2015 to 8 April 2015.

2. From the above, it appears that you were fertile on 7 April 2015 at the time of unprotected sex.

2. Though it is not fully certain that you will have a pregnancy, it is better to get tested for pregnancy if your periods do not happen as expected or any day after 22 April.

*Please ignore 19 April 2015 as mentioned earlier and do the test on any day after 22 April 2015.

Hope your query is answered.
Do write back if you have any doubts.

Dr.Vivek
