Girls, Please tell me about it. It's really urgent for me to know?

I was thinking a lot about it, that should I post it here or not?
I live here with my brother, who is just one year younger than me. We both are like best friends.
So this happened yesterday, after work, I went out with my boyfriend, and came a bit late than usual. Obviously we did had sex few times. But after dinner he dropped me to my home.
My brother was waiting for me, to have drink with me. We usually do this quite a lot, we both have some whiskey before going to bed. Last night, I told him that I was with my boyfriend. He didn't seem to be happy. After that we had drinks. I can handle few but if it is too much, I completely loose my mind. Many times when I was drunk, my friends told me next day what I did. I literally don't remember anything.
Same thing happened last night. Me and my brother were drinking. I told him, I can't handle more, still he insisted and I had too much. I literally don't remember a single thing after he was insisting me with so much love, I couldn't say no. Then next thing, I woke up in my bed.
I asked him what happened, he just said I was too drunk so he helped me to my room and I slept.
But since morning, when I got up, I had too much hangover. Still my head is dizzy like I am still on ride. Morning time, I felt a bit itchy down there. I was feeling very different down there, in my vagina.
I ignored it, but this morning as soon as I came to my office, many of my girl friends complimented me that I am having a different glow in my face today.
Then after thinking a lot about it, I am having the most disgusting doubt ever.
I had sex with my boyfriend in evening time, around 4-5 pm. But I was feeling like that this morning. This never happened to me. Then I had doubt that did my brother did anything. Because I literally don't remember anything at all.

Can anyone tell me how do I confirm this? I can't ask him directly. If he didn't do it, this would totally ruin our relationship.

😱 Hmmm the whole fact that you are even questioning whether you and him bumped uglys would be enough alarm bells ringing for me hun I would search my feelings, you already know the answer even if you think you don't remember, it's in there somewhere and you know your body too, so listen to them both and I would go with what my gut feeling is on what they are saying to me.

Brain says yes, heart says no

I think you're just jumping to conclusions.
