She's late. Very late.

I haven't had AF since last month im almost 2 weeks late, I've been vomiting a lot, I even threw up stomach acid. My breasts feel swollen, and very sore. I've taken two tests they come back negative. And AF was weird last month. It was a spotting and lasted 2 days. I've been emotional, very tired and light headed. I've had no cramping either. Last month I didn't hace cramping or sings of AF. I hope you lady's can answer me, or tell me if you have had this experience when TTC! I'll be calling my gyno later on today! My boyfriend and I have been TTC for 18 months. We found out I have PCOS Feb 20th. But not bad enough to try anything. So fingers crossed!!!
