Pregnant or just past ovulation?

Hey guys, so I have never really experience this, I had my last period August 27th-31st the first two days were kind of heavy and then the next two I spotted and my period was done the 30th. On the 31st I spotted just very lightly. The kicker is that on the 23rd my husband and I had sex and when we were done there was some blood on him from me (just a tiny bit) so I put a tampon in and when I changed it there was no blood and had no blood again until the 27th. My ovulation date was yesterday. Just today I had some discharge that was creamy and thicker. My boobs have been slightly sore with sensitive nipples and I have felt some really weird feelings that I have never felt before in my uterus/abdominal area. My period is not due until the 25th and I have been having these feeling for about a week and a half now. We are currently TTC. Could this be a pregnancy? Or just some weird period signs? Some insight would be wonderful! Thank you so much!
