TTC with baby #2

Anyone out there have a toddler and currently expecting baby #2. I am currently 4 days late with AF (I'm one of those people who usually have to be at least a week late to have a BFP) but I have several symptoms that I experienced with my first pregnancy. If you had a toddler while pregnant with baby #2 did your toddler suddenly become more clingy to you. My daughter will be 2 in May and she has just suddenly felt she has to be right on top of me all the time. I literally have to beat her out of my lap no matter where I'm at. Anyone else experience this and found out they were expecting??
