So me and my partner try to use condoms but end up using the withdrawl method alot (this is new to us). We arnt officially TTC however we are both in a place where if pregnancy was to happen we would be okay with it. We recently had unprotected sex in which he pulled out seconds before he finished. I didnt realise till the next day when I got EWCM and checked the app that it was my fertile window. My period is due in 7 days and I have been having a few pregnancy symptoms which I'm not sure if they're in my head or due to my period starting soon. I've taken couple of tests which have been negative although I expected that at this point in my cycle anyway.

What are the chances of me being pregnant now and is withdrawl around ovulation time risky?
