So we are trying for baby number 2 ! Came off my pill over a month ago now and had a small withdrawal bleed .. since then Ive not had a proper period , me and my partner had sex 12 days ago but I noticed I had a bleed of brown blood since then only for a day.I took a normal test which come back negative but Ive been having symptoms of feeling a bit sick and Ive had some pains in stomach like I m coming on.Do you think I should re test soon ?
