Advice please

Good morning ladies, my boyfriend and I had sex and he released inside me about 10 days ago on Thursday it will be 2 weeks and I am supposed to start this Saturday. I am having preggo symptoms though... frequent urination, headaches, food cravings. I have been through this 4 times already so I know what its like lol but all my tests keep coming back negative. I have history of false negatives as well. But the kicker is every time we have sex we never use protection and hes released inside me every time and I have never gotten pregnant. Could one of us just not be fertile or both of us? Should I just wait to see if I miss my period? My mind is racing and I keep telling myself I am not so I dont give myself a fantasy pregnancy. Idk what to do at this point. Any and all advice would be appreciated thank you!
