first baby signs? what are the most early ones???

Gabriella
So I did A trigger shot and went to a doctor to do a technical sperm implantation or how is it called in English...  and it was too late... my ovulation had happened. They found the empty bounce looking thing which was the sign that ovulation had happened already they explained. 
According to my counting I should be pregnant as we had sex a day before and a Day after the ovulation. 
Now I am at 4 days after my ovulation. And I am experiencing extreme discomfort while sitting for a long time, it feels like my belly is bloated a little and I gather gass more than ever... 
also I get some pain every now and then, like stabbing in my right side of bladder or something... 
my gyration is.. am I just overdoing it and searching for some stupid excuses just to give myself some hope that finally we nailed it? Or is it actually possible that I might be experiencing some first extremely early signs of pregnancy
And what is the most early pregnancy sign I could expect?? 
Love you all please answer :D I'm going wild on my imagination :D
