Normal?

Braxton Hicks with pressure on vagina and lower abdomen. No pain just have to breath through it and heart rate increases. Also having light vomiting after eating. Doesn't feel like labor that I had with my other two but feels close. Went to ob cervix is firm and closed so no dilation. Contractions make me have to pee rather badly and having an increase in stool... As in 3-5 times a day.
