Hi and thank you so much for this query.

NO matter the length of your cycle, ovulation always occurs on the 14th day from the first day of menses. In this light, you were most fertile on the 2nd of October considering the last date of your menses.

Pregnancy is a game of chance and no amount of speculation can guarantee 100% success. However, have regular sex as many as 3-4times/week or more and you would increase your chances.

I hope this helps. I wish you well and success with this. Thank you so much for using our services and do feel free to ask for more information and clarifications if need be.

Brief Answer:
3days period!

Detailed Answer:
Hi and thank you so much for this follow up question.

I will recommend that you have sex for 3continuous day during this period. For instance, if it were to be the 2nd of October,, then having sex on the 1st, 2nd and 3rd would be highly encouraged. Eggs, once released can survive for a maximum of 36hours and that is the only opportunity you have to get pregnant. Sperms can at times survive for two days.

I hope this addresses your concerns. I wish you well and would be happy addressing any further related to this that you may have.

Brief Answer:
Yes, you have achance!

Detailed Answer:
Hi and thanks for this follow up.

You have a chance of getting pregnant still. However, multiple days would have increased your chances. Also having sex more often than not would also increase the chances. Remember it is a game of chance and no one can for sure say this is what it takes but recommend ways to maximize your chances.

I hope this helps. Let me know if you have some further worries that you would like us to address.

Detailed Answer:
You no longer have any chance of becoming pregnant this month. However, you can continue to have sex for the pleasure of it.

Next month, try and pay extra attention to this window and make sure it doesn't escape you full attention and commitment.

If you have never been pregnant before, you would need to try for at leas 12months without succeeding before you can be investigated for any difficulties getting pregnant.


I wish you well. Hope this helps. Any further worries, am at your disposal.
