Trying to get pregnant

Please I went to do HSG test and I was told my two tubes are block. So I went to see a gynecologist and they scheduled me for a procedure to open the tubes .which I did last year december 2019.and now I am taken ever green mum to be tablet. But my concerns is that I don’t know if the tubes are open or not.is it adviseable to go and redo HSG test to confirm if the tubes are open as said by the gynecologist or not.??
