Hello.. Well I think it's better to go for ultrasound scan to rule out pregnancy first because upt is just a initial test for pregnancy.. It may show false negative also...secondly if its negative... You can plan for the next baby after discussing with the gynaecologist... You need to plan out intercourse in the fertile period of your cycle so that chances of pregnancy are more...then you also need to take good care of yourself.. Eat well...thank you
