So since the beginning of second trimester, I’ve been feel constant hunger like every two hours or so . Ever since yesterday, I’ve almost I no longer have that . I ate like three times yesterday and that was it . The same for today . The only thing different I did since yesterday was, I changed my prenatal and started taking tums . Could that be the reason or it’s just a pregnancy thing? I also have my obgyn appt yesterday morning and everything went well .
