High risk and first baby!!!!

Angela

Hi I’m Angela and I am having my first baby and I have endometriosis stage 4 with a endometrioma . I’m 17 weeks and always scared about the baby. I was weighed at my docs and I was just 124 and yesterday I weighed myself at home on my scale and it said 122 . Losing weight at this point ..... is it normal when you have a high pace job and are eating healthy foods like salads and fruits and proteins?? Or maybe the home scale is off??? And also idk if I’m feeling butterflies they said that is the feeling you feel when baby moving I can tell and don’t know if I’m just over thinking . This is my first cabby so any feed back will help! I just want to know my baby is still ok.

Also how true is hearing the baby’s hart beat with a stethoscope at 17 weeks ??? How are you supposed to find the baby to hear it???
