Has anyone felt like this (pregnancy)

My husband and i tried to conceivedon our honeymoon. I ended up having my period. We havent tried anymore. We dont use protection no birthcontrol no nothing sometimes condoms or nothing at all wer just careful on my ovulation days . Last month the whole month we werent trying but we were not careful either on ovulating days we would do it . And now im sad that the pregnancytest came back negativeone looked like positiveand the other literallydays not pregnant. We got a little excited we saw the positiveand now today on the morning before work i took it showed him and we both got sad i started crying i know we werent trying but i got excited to have a baby .
