I don’t know why i’m having all these

Ai

36weeks pregnant. Mucus plug since last week. But it stops for few days and coming back. On and off. I felt pain in vagina today. Hardly can walk. And the pain is on off at back area, waist and below. And i’ve vomitted 2 times. All after eating. And i can’t sleep! Now is 3.22am Malaysia time. Eventhough this is my 3rd pregnancy, but i can’t tell what are all these 😩😩😩😩😩😩😩😩😩😩
