Good morning ladies question of the day
They went to my doctors appointment yesterday I found out that I could be pregnant they going to do it ultrasound this Thursday she said that I do not have a virus or flu because  last 48 hours she said I been throwing up for about two weeks and two days she told me to take some vitamin B6 and to also mix salt and a little bit of sugar in the water because I was so dehydrated from vomiting for two weeks and two days so I went to the store to pick up the vitamin b6 and something told me to get some prenatal vitamins I don't know why but my instinct told me to buy some I threw up two times at the doctors office I just told myself I'm going to take some prenatal vitamins after I took them I have not throwing up for the rest of the night my question is that could I be pregnant because some reason the prenatal vitamins help my body from not throwing up last night if I am pregnant with the baby likes the prenatal vitamins and also does the prenatal vitamins help you with not vomiting because it felt like it helped last night when I took two also I did not take the B6 vitamin last night Q for your guises help
