As your tubes have been untied, patency of the tubes is restored most likely and you should be aware of the occurrence of an ectopic pregnancy
, an usual complication of recanalized tubes due to defective tubal motility. You may repeat the pregnancy test after a week and if it is still negative go for a blood test
and a sonogram. The spotting may be due to hormonal
disturbance or an implantation
bleed. See your doctor for further management. Take care.
