I feel so down and depressed

So I have only been off my period for a week and it started again on Sunday before my husband left for drill for the army well later that evening when he got home I told him and he told me it’s okay because when the time is right we will get blessed with a baby we have been trying for 4 months witch I know isn’t long but seeing negative test is so depressing and on top of that my breast have been hurting so bad and it’s to the point I won’t even let him touch them. I don’t know what to do we are both still young but this is what we want. We want our family to start but right now just isn’t the best time but when it is we will be blessed I need advice on how to stay strong. I have also been really emotional and I don’t know why!!
