With ex partner conceived DD within 3 months of trying. Year later we decided on another and spent 2.5 years trying and no baby, we split up after that (I really did think we would of lasted but he suddenly switched like a light switch and was unrecognisable to the man I got with). Now with dp of 2 years, trying for a baby for the past 12 months - no baby yet! On my period now. Has anyone really struggled to conceive their second child? Could my first pregnancy resulted in infertility some how?
