I Was Expecting To See My Period On 24th Of

I was expecting to see my period on 24th of April bt did not come out so I did a pregnancy test on 25th of April nd it shows negative, yet I did not see it until 30th of April I took Menstrogen nd I later saw it on 1st of May. But on 9th of May I did a pregnancy test nd it shows positive bt the doctor said it has flushed out due to the drug I took. I later took d drug again on the same day bt ever since then I hv not concieve again. Pls wot should I do.
