Hi, This month we started planning for pregnancy. I have all hormone tests and tvs got done which are normal. Regular periods of 28 days cycle. I have missed by periods by 2 days. My ovulation was on 11th (confirmed via follicular study and home ovulation kit). I have immense lower back pain and heaviness from more than a week. Especially on the left side of lower back and hip it's very painful. Sometimes it's stabbing pain. Whenever I stand or walk pain increases. I did pregnancy test at home it was negative, beta hcg is
