Pregnancy Probability: Calculating Your Chances After Unprotected Sex

Question
Hi,

I am 32 old married woman.My last period started on may 1st 2007 and lasted for 6 days.Normally I have a 30-32 days long menses cycle.My husband and I had unprotected sex on may 14th .What is my chance of getting pregnant this month?I am 5'4" high and my weight is 160 lbs now.I am trying to lose my weight currently.For that I am using an elliptical machine for 45-50 min regularly and burn around 700 calories by that.Not restricting any food items from my diet,but trying not to take any fatty food and eating more vegetables and fruits.So ,I want to know ,whether it is wise to continue my exercise routine  knowing that there is a chance for me to get pregnant this month?Can it affect my pregnancy in any ways?
Thanks in advance,

Answer
Dear Nimmi,

Your chances of pregnancy are actually fair. Based on a 31 day cycle (averaging), we would expect you to ovulate on approximately 5/18. Under ideal conditions, sperm cells can survive up to five days once past the cervix. So, you do have a fair chance at conception. However, if you are trying to conceive, my suggestion would be to keep trying this week! Unprotected encounters tonight and again on Friday would increase your chances dramatically.

As far as the exercise - no need to quit at all. It sounds like you are staying fit and that is fantastic for pregnancy. The only time you'd need to back off is if you would start to bleed and/or cramp during pregnancy.

I hope that this information has helped you and answered your question. I wish you well.
