Can't sleep....

Monique
Hello all, please help me.... I'm 13 weeks and now the last 2 days I've sleep a total of 5 hours. Is it just me or do I have to take Tylenol PM from now on just to sleep atleast 3-4 hours straight??? It's like I take naps now. And it's never longer than 2-2 1/2 hours. Btw I'm a first time mom so please be patient with me. Thank you in advance!!!
