Who has conceived using pull out method ?

My husband and I had sex the day I was ovulating and we only used the pull out method.

We have used this method for seven years without fail (only got pregnant when he didn’t pull out), so I’m a little skeptical that I would be pregnant but I’m having pregnancy symptoms similar to what I expected with my first child early on. However, I’m not sure if it’s just in my head! He is sure that he pulled out in time 🧐Going to take a test if my period doesn’t start by next Friday but wanted to ask who has the pull out method failed for???

(We were going to start TTC in February so if we are pregnant it will be just a little earlier than expected)

Edit: not pregnant, he pulled out well 👏😂
