HELP am I just freaking out or am I pregnant?

My period was scheduled to come on the 22nd. I was worried all day that I wasn’t going to get it and then last minute at around 10 pm, I noticed that when I wiped it was bloody but it was sorta light. Not pink, but just light. I didn’t have pads so I used a tampon to sleep in and thought I’d be fine. However, when I woke up and took the tampon out, there was still just a little bit of blood. Ever since the morning, I have stopped bleeding. It’s been 7 hours and still not a drop of blood has come out since. I’ve been panicking all day thinking I’m pregnant, but I didn’t technically skip a period. I am thinking due to stress I am being delayed, but it is freaking me out that what happened last night could potentially be implantation bleeding. Can anyone tell me if they’ve had this problem before? I’m not on birth control, and I did have sex throughout the week of June 6-10 but not once did he ever finish inside me. I am going to take a test later today and hopefully that’ll give me some peace of mind, but I have never had an irregular period so it is stressing me out severely. I’ve had plenty of mental breakdowns considering I cannot be pregnant at 22 years old. If anyone could help, I’d appreciate it tons. Thank you. 💖
