I really just cried on the phone to my husband ....told him im tired of trying i am tired everybody around me is getting pregnant and and some dont even want to be pregnant or want the child and im over here struggling to concieve. He told me god works in mysterious ways we been trying for a while and he doesnt want to give up we have one child already just wants another which would be our last kid we planned on having. I  am just so tired i tried taking vitamins everyday nothing worked then i heard about preseed so i stop the vitamin then i tried preseed like 4 times and now n nothing so now im thinking of doing vitamin everyday and continue with preseed
