New to this... need advice

Hi everyone I am having symptoms and I want to make sure if I'm ok. I just stop taking the pill a little over a month ago and started prenatal vitamins. I keep having cramps, breast pain, nausea, and it feels sore down there. Nurse says my body is all out of whack because my hormones are trying to regulate now that I am off the pill. I have had my first period off a week ago and it only lasted three days which never happens to me. Normally it's five and irregular. It abruptly stopped which was nice and odd. After the period I am still having  the symptoms above plus lightheaded. Just need to know if you ladies had gone through the same after stopping the pill and getting on prenatals. I think I want to have a baby so bad I am going nuts. Thanks for reading and your posts 🤗
