my husband and i already have two kids together, but we've been working on a third one-a girl hopefully. for some reason evey month there is always a let down when my period comes on and we don't understand exactly. with both of our boys each time i was dieting using diet pills, within two months afterwards i'm pregnant , but this time i'm ttc without using them. can someone please if they can explain to me why the only time i can get pregnant is when i'm on some diet pill it's ridiculous to me.View Thread
