Chances of pregnancy… Sex four days before ovulation

[sunshinecitrus1]

TTC and I ovulated a little later than expected this month. Only had sex once within my fertility window, four days before ovulation. What are my chances!?

Hmm I'd assume not pregnant, but technically there is still a chance.

According to the British Fertility Society, it is around 18%.

They say anything upto 5 days before ovulation can lead to pregnancy as sperm can live that long inside you.
I went through ivf last month and released an egg ( despite being on medication to prevent this) and got pregnant ( miscarrying) I was well monitored and had to have ovulated around trigger as all follicles were counted until trigger day. We had sex 5 days prior to this and it wasnt even deep penetrative sex as we had to avoid this due to risks such as ovarian torsion with the stims and we got pregnant so yes I think its possible. We were having icsi as we have both male and female factors. I wouldn't count yourself out. It's more likely the closer but not impossible
