my wife have no periods from 62 days. Have done pregnancy test, for twice it was a faint positive line, then negative. So he went to a gynec, who first told u r most probably pregnant by carrying test. After 10 days she consulted to a same gynec, who again carried out test which was negative. After sonography gynec told tht my wife is not pregnant. Gynec did not carried out blood test. Also doctor have advised my HSA test of mine. I would like to know wht does HSA test means? Is my wife is pregnant or should we consult another gynec?
