Kinda bummed

For the past month my boyfriend and I have been freaking out because my period has been super late, like later than usual. With my medications and depression, birth control isn't the best option for my recovery. We do use condoms and are careful. I have a lot of weird symptoms that I never get like tender nipples, food and certain smells making me nauseous and EXTREMELY tired all of time. I have taken 3 of the same tests and they all came out negative. I am a little heart broken because my boyfriend was holding my stomach last night and looked at me and said there could be a baby growing in there and my heart melted. . He is still wanting me to test again so I feel he is also disappointed. We aren't ready though. We both can not afford a child or give it a stable home so it coming out negative was also a relief. It is just weird because we are sad yet relieved I guess.
