35w 3days and LOTS of pressure

So I've been having a lot of pressure down there and been so uncomfortable. So this morning my fiancé and I took the kids school clothes shopping and while we were out I started getting sharp pains. So we get home I start cooking lunch/dinner because he leaves for work at 1:15 in the afternoon. So I laid down after he left for work, I woke up around 4:30 and I have soooooo much pressure it's bringing tears to my eyes, am I in labor or is he just moving down at an accelerated rate? I don't wanna rush to L&D for no reason I already feel stupid for not knowing what's going on with my own body.
