Might be pregnant

So I have symptons of pregnancy. I normally start my period on the 23rd. Of every month and I had sex on the 9th and 13th, my ovulating week. We'll I spotted like a week and a few days after and that was my first sign. Then I start urinating alot to the point It felt like a uti was coming on. And that was my second sign because I read the your uterus lowers and puts pressure on your bladder making you urinate alot. I had sore heavy breasts, my cramps were a different then period cramps and I miss my period for the first 3 days. Then I had my period. It was like a regular flow for 2 days then now I'm spotting. I'm on my 3rd day on my cycle. And I'm trying to wait out on a pregnancy test. I was really excited at first but now I feel like I'm not even pregnant. am I misreading my body? Am I to early to check for pregnancy?
