Confused 😩😩

So I have been having sex a lot and my boyfriend doesn’t pull out every time we have sex , we did it when I was fertile is it most likely I’ll be pregnant ? I went to the doctor yesterday my pregnancy test was negative but we had sex like 3 days ago when I was fertile 😩😩 and he cummed in me like twice 🤦🏽‍♀️ and my stomach feels alil funny what should I do
