Anxiously waiting

I first noticed brown spotting on 6 June, which was unusual because it has never happened in any of my previous cycles. In the days that followed, I began experiencing nausea, dizziness, exhaustion, and constant hunger. At first, I didn’t think much of it and assumed my period was simply coming earlier than expected cause my cycles are kinda wonky at times. However, my period never arrived that week. As the days went by, the intensity of my symptoms continued to increase. At the same time, several people started asking whether I was expecting because they felt I looked different. That made me suspicious, so I started taking pregnancy tests. I tested three times, and all were negative. I decided to wait until my expected period date, which is tomorrow, 18 June, before testing again. Last night, after using the toilet, I noticed light pink blood dripping down, which was different from my usual bright red menstrual blood. I decided to put on a pad before going to bed and monitor the situation. This morning, I woke up to a completely clean pad with no spotting or bleeding, yet I feel more nauseated than ever. Part of me is tempted to take another test today, but I think I should wait until tomorrow. The waiting is incredibly frustrating. I do feel and look very pregnant though so I’m hoping it’s not false alarm. But you know overthinking sucks.
