After miscarriage

Stormy
Ok so I found out I was pregnant Jan 26th and had miscarriage on feb. 2 . I was 5 weeks. Doctor did urine test and it was neg. so they didn't do blood work or u/s. So my question is tomorrow it says is my last day of ovulation and I'm feeling sick to my stomach and lite headed? Is it possible to be feeling signs this early? Or am I crazy???
