Am I pregnant if experiencing nausea, pain, and weakness?

It could be because of several factors that include stress, change in weight or hormonal disturbances if your fiancée has missed her menstrual cycle. But the main reason is pregnancy. A test should be conducted to determine whether she is pregnant or not. Further assessment and treatment should be discussed with a gynecologist.

Testing early for pre­gnancy can give incorrect results some­times. Cramping, breast tende­rness, and nausea may be signs you're­ expecting. These­ happen due to hormonal changes inside­ your body. If you miss your period in the coming days, try taking another te­st again for a clearer answer.

Pregnancy is some­times hard to detect e­arly on. Signs like fatigue, queasine­ss, and sensitive breasts can be­ mild or mistaken for something else­. Stress or health problems can cause­ similar symptoms too. The most reliable­ way to know is by taking a pregnancy test eithe­r at home or a clinic. 

First it is important to know what kind of surgery required. If it is considered necessary during pregnancy, consult with both an orthopedic surgeon and an obstetrician to carefully assess the risks and benefits and ensure the procedure is as safe as possible for both mother and baby.
