Confused

How do I start this conversation without sounding desperate or inpatient….. my partner and I have been trying for 6 months now (we haven’t gotten a positive), I’m about to start my period in a week, I took a test this morning but it was negative, I know it’s too soon to test but something in me feels different and I really think I’m pregnant and having all this symptoms which make me think I am but at the same time it’s like I’m about to get my period 😩
