I give up!!!!

My Husband and I have been trying to have a baby for nearly 5 years. I have a daughter from a previous marriage. I do ovulate. My period is always in time. I give up. No we have not had any fertility treatments. I’m just disappointed and let down every month when AF shows her ugly face. I’m due to start my period any day now. I’ve taken some tests. All negative of course. I’ve been cramping for a week. A whole week for some damn reason and I just know AF is going to show up any day and piss me off. Because not only have I been cramping for a week with my fingers crossed hoping for a positive test but I know I won’t ever get one. Then I’ll start my period only to be mad that I’ve cramped all week just to start my period and have even more cramps except these will be actual period cramps witch suck!! I don’t get it. I don’t understand. I just want one more baby to complete my family. Everyone around me gets pregnant immediately it seems like and I’m over here pretending like I’m fine and I am not. Im tired of spending money on tests. I’m tired of getting my hopes up. I. Give. Up.
