Getting pregnant while sick?!

Sarah❤️ • I am happily married with a beautiful son. I am currently pregnant with my rainbow baby! 💛💙💜💚❤️
I have had flu like symptoms for the past 4 days. I have a friend who had said that it is easier to get pregnant while sick. Is there any truth to that at all?! She says the body is fighting off the sickness and not as concerned about "fighting" the sperm. We've had sex twice since I've been sick.
