Babies!!!

Dasha • Hi all!! I'm 38yrs old, mother of a 17yr old daughter.
I have a13 year old daughter and I'm having a Hell of a time getting pregnant again, has this happened to anyone else? I had no complications during my first one beside preeclampsia (high blood pressure) but that was right at my due date. Funny thing is I was on birth control when I got prego, had been for over two years. Am I the only one this is happening to??
