I'm 6 weeks pregnant. 29 years old. I've had the stomach cramps and they've gone away after 2 weeks. Now for the past 2 days I'm having really bad bad pains. Feels like I've been standing on concrete in 1 spot for 12 hours straight. It's right where the sciatic nerve is. Sometimes my right leg has a throbbing pain with it. The only symptom of pregnancy I still have is sore breast (but only at bottom) just worried bc I've had a miscarriage before. Please give me advice or let me know if this is normal
