What is this?

Recently I’ve been experiencing some intense pregnancy symptoms but I haven’t been ruling out pms because the symptoms are basically the same. But I’ve always been told that when you’re pregnant or possibly pregnant you just know and I definitely feel it like I’ve never been pregnant before but I have had a pregnancy scare and this feels extremely baby in the oven type of thing. I’m not scared but I went to pee today and had a pink discharge on my tissue. My period is irregular so it’s been late by 40 days so far. I had sex two weeks ago to be exact and a couple days later I felt symptoms I just thought my period was coming because usually when I have sex it does that. But then again I noticed on my calendar that my period was supposed to be on a expected date and it did not come. I have irregular periods due to medication I’ve been taking since I was 15 . I also read that the pink discharge was a sign of implantation all of the symptoms I have read that I know for a fact that I have. I have became sensitive to smells I would never have expected to be and have become very irritable. I plan on going to the ER because my gyno can’t get me in until the end of the month. The anticipation is killing me. Does this sound like pregnancy I’m new to this I know when I’m pms’ing and this is not it. I also usually get swollen breast but my period usually follows up directly after. I even noticed weight in areas of my lower half that I didn’t have before and I’m very skinny I don’t eat much so I’m really suspecting that I’m pregnant. If you have any advice please provide me with some I would appreciate it.
