I feel like I’m going crazy

So here’s the deal, I went off birth control early January, I ovulated the 15th- 19th. Peak ovulation day, I had unprotected sex. And the days before and after that. Well according to the app I’m supposed to start my period in two days. I’ve taken so many pregnancy tests and they’re all negative. I’ve been ridiculously emotional which could be a result of going off the birth control. But I feel crazy, I took 3 tests today. I’m on medications that could potentially harm a baby if I was pregnant, but if I’m not it’s a medication I need to be on. I’m so stressed and emotional. I didn’t realize seeing negative tests would weigh so much on me. Anyway, here’s the most recent. It’s blue dye which I’ve heard bad things about. But am I just completely crazy or is there the slightest hint of a line? The top one is from a few days ago to compare, bottom is today (within the 10 minute time frame) I feel like the circle is just blue? Like it’s not clear it’s just a blue circle. I’m so confused and so stressed and anxious. Was just hoping for some support on here, anything will help. I’m gonna test again tomorrow morning with a pink dye test
