No baby

My husband and I have been trying to conceive for almost a year!!! I take more of a natural approach, if it happens it happens I don't buy kits or anything but I really am starting to get depressed more and more especially when my period arrives!! I have 2 kids 11 and 8 and I was on the pill for 7 years, my periods are normal I'm just depressed ready to give up anyone else in the same boat!??? I feel myself getting angry with my husband and its straining our marriage all coming from my end!!!! Grrrrrrrrrrr
