Pelvic and bladder pressure!?

We are month 6 of TTC our 1st and I have had some abnormal for me body feels. My period is to arrive in 6 days and I am always on time like clockwork. I did not test for ovulation the last three months but when I have, I have ovulated a few days earlier than my expected date in the app (photo attached). Odd issues started this past week…I have had a weird aversion to alcohol (I get drunk really easy and sick feeling off one or two drinks), I had 2 days of Nausea and acid reflux (specifically at night), I have felt tired a few days as well (slept in until 12:45 yesterday - very abnormal for me…I am a 7:00am girl), very vivid dreams for nearly a week now, and for 4 days I have had some pelvic pressure (not painful, just very heavy and strained feeling - almost like you worked out after you hadn’t for awhile). The pressure is nearly constant. I was wondering if it was merely a UTI but I pee normal with no burning sensation. I did have a bit of constipation but that has subsided and I still woke up today with heavy pressure in both my pelvic/abdomen area and bladder (it felt like I had not peed in over a week). All that to say, have any of you experienced pelvic pressure with early pregnancy and so soon? I know it happens later but seems oddly suspicious this early. And from what I gather, implantation cramping feels a lot different (maybe I am wrong). I am not the kind of person to think every little body change is pregnancy. I just feel weird and can’t find any forums online discussing pelvic pressure.
