Sarah • Proud wife and stay- at- home mommy to Oliver and Owen!

I thought I would get my LH surge this morning as I thought I ovulate tomorrow. does time of day matter? should I take another this afternoon or wait til tomorrow morning? we will BD tonight and tomorrow either way. we didn't use opks when we conceived our son and didn't have a problem getting pregnant and we are BDing the same way we did when we concileived him. opinions please? lol
