Can't stop thinking about being pregnant

My husband and I are planning on ttc in July but I can't help feeling like I'm pregnant now. Part of me is thinking it's all in my head because I want it so badly and logically there's no way I should be as I've been having periods and have 2 negative pregnancy tests. On the other hand there is just this constant nagging, there non of the usual signs that I have ovulated this month, (egg white cm), my breasts are bigger but not at all painful leading up to my period like usual. I also get occasional heartburn and siccups and my lower back aches while hoovering which never happened before. I get dull aches in my hips and my weight has increased dramatically even though I'm working out more and eating less. My husband keeps telling me to be patient, (I haven't mentioned any of this) but I can't get pregnancy and feeling pregnant off my mind, it's like torture. Has anyone else felt this way or have any advice? Thanks
