REALLY needing answers!

So, I've posted question a few times, and started to get sad that no one can answer or comment! We are TTC baby #1. I'm 4-5 DPO, and AF is due in 10-11 days. We had sex all during ovulation. Now I'm experiencing period like cramps, and lots of thick mucus when I wipe. Could this be early signs of pregnancy! I'm trying not to get my hopes up, but since I've obviously never been pregnant before, I was just wondering if it could be possible! Please please give me some answers or share your experiences. Thank you!
