Feeling pregnant right after DTD??

Yes, I have! My LMP was June 6. We DTD very often and ever since CD12, I knew I was pregnant. (I O'd very early) When I mentioned to to my SO, he said he had a feeling because he had been feelin weak. Only time he felt like that was when we were pregnant the first time. At 9dpo, I got a faint BFP. I took two more a few says later and now I am just about 5 weeks!! Am I the only crazy who KNEW BEFORE a BFP that they had a bun in the oven??
