I had done oral sex with my hubby on 24 may his sex part was near to mine but his sperm dsnt came out at that time after in regular days my periods were started on 10 june but at that time I had putted vitamin c tablets inside my vagina n had drink 3000gm of vitamin c tablets which make me less periods at that time .now I am having pain of periods my legs and stomach are paining from one week in short periods of interval but I dnt have periods. Had doc sad me for pregnancy test I had done that too with prega news .n my result is negative. So what should I do now .should I take medicine for early periods.
