Trying to lose some weight and conceive

Hi! Ask ko sana, nag plan na kami ni mister mag baby na, kaso ang weight ko now is 75kg, nag eexercise ako everyday, 1week na. Ok lang ba yun? We do make love this weekend kasi fertile ako, so ang pinaka ask ko pano ko malaman if kung preggy na pala then nag exercise ako.. any tips po.. thank you ! ?
