Missed my period i just realized i started a new medicine and it delayed my period . I ovulated on April 15 but when taking the myo inositol it delayed my period . So I’m assuming I didn’t ovulate on the 15th of April . Took many pregnancy test and they all were negative 👎 now i took a ovulation test on May 7 it was a blazing positive . when should i take a pregnancy test ?
