5 dpo and 4 days after DTD

I took ovulation tests this passed weekend and they all showed ovulation at the time. My husband and I DTD on Sunday. It is now 4 days later and I am experiencing a heavy, full feeling in my lower abdomen. It's sensitive when I try to suck in my stomach and it feels harder than usual. This fullness is making me run to the bathroom way more than normal. I go each time with zero problems, so my initial thought of a UTI is questionable. I am also experiencing slight dizziness and I'm starving all the time! Has anyone else experienced this? I am such an impatient person so the wait it killing me!
