Hi all I’m in need of some advice , I was tracking ovulation, ovulated and tried to conceive… I started to take pregnacare before conception tablets a week later. Have been using them for 7 days, and my period is late by about a day. Pregnancy test is negative. Could it be late because of these tablets ? I’ve read the reviews how it delays periods :/ but would taken them for 7 days do that that quick? And also if I took them after I ovulated would that still impact my period? HELP PLEASE
