Newbie here

This is my first time ttc. I’m like 6 days late and was feeling light headed and weird also my blood pressure was really really low which has never happened to me. I was thinking oh this would make sense if I’m pregnant. But I was nervous so I didn’t test. Then I had a follow up at my doctors for an unrelated thing and was like maybe I’m pregnant so they did a blood test. I then spent the next 28 hours super nervous and compulsively checking my doctors app till I got the results back, negative. I’m really bummed but I know it’s just my first month trying so I shouldn’t be too worried. I also had a cyst last summer which was pretty bad but resolved it’s self. Just need so motivation and reassuring. And how much does having had a cyst impact my chances.
