Ovulation Help!

Hi!

So my boyfriend and I have been trying to conceive and this will be our second month trying. I used the clear blue advanced ovulation tests. On 04/02 I received low but the next day until 04/06 I received high. Starting 04/07 I received the static smiley indicated peak. I always take my tests in the AM with my first urine. I noticed on 04/07 in the evening I had a full aching pain in my uterus. The next day on 04/08 it became worse. The pain felt like it was in the lower part of my uterus and it stemmed to my back. It was not painful enough to stop me from doing activities but it hurt. It almost felt like period cramps. I read online ovulation pain could be felt on one side or the other. This almost felt like it was in the middle of the uterus, but I’m not 100% sure. I’ve never experienced this before. The pain started to decrease throughout the day and today 04/09 I have no pain. I have no medical conditions regarding my cycle. My cycle is always 27/28 days long and normal. Has this happened to anyone before? Does this mean I was ovulating? Should I be concerned at all? Also, should I BD today just to be safe?
