Hi welcome to Health care magic forum. Ectopic
pregnancy pain usually occurs only in abdomen upto the theigh fold. Of course very rarely there may be a refered pain, bud pain in the stomach must be there. Delay in the period only can't confirm the pregnancy, you can have a home pregnancy test of urine done for confarmation. if it is negative you can go for
HCG test of blood for pregnancy test done in the laboratory for reliable result. I advise you to consult an orthopedic surgeon if peregnancy test is negative.
Besides i advise you some diet recommendations as avoid taking more of potato, other tubers, tomato, coconut, cauli flower, egg, fish, etc which tend to increase the pain threshold.
Take more of green leafy vegetables, pulses, sprouts, milk, meat, fruits, juices, and dry fruits to improve blood, general health, resistance to infections, ans stamina to with stand such pains. Wishing for a quick recovery and thanks for calling.
