Hello,
Since you are 8 weeks pregnant & experiencing severe cramps & lower back pressure but there is no spotting or bleeding you need to get into contact with your doctor.
You can take antacids, sometimes
gastritis (GERD) can cause abdominal discomfort & pain. Avoid doing any heavy work, stay at rest. Take
folic acids as prescribed by your treating doctor.
Maintain good posture while sitting or standing. Stay well hydrated, avoid intercourse. Maintain a healthy weight, avoid
stress &
anxiety.
Stay away from addictions if any. I suggest you inform your treating doctor. There is no need for a per vaginal check-up, if needed get a USG done to see the well being of the fetus & the position of the placenta.
Placenta previa or abruptio placentae may cause per vaginal spotting or bleeding. Take precautions.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. Nupur K, General & Family Physician
