Is it anxiety?

I don't know what is going on with me .. I'm 36w+3days

Randomly I have been feeling my heart race for no reason . seeing my pajamas moving to the paste of my heart beat and I'm feeling very anxious I haven't thought about anything mentally to do this to myself I don't know what's happening but its freaking me out ???? Another thing I noticed about today is I've been going number 2 often today more than ever. Now that I'm starting to think about it ... I'm getting scared to go into labor . and its making me feel more anxious . my baby has been so active today LIKE CRAZY. Feeling like she could come today , tomorrow the next day and so on .. Is making me freak out. Ok I have no choice but to give birth now . please don't misunderstand this as "I don't wanna have my baby" because she was planned and I love her so much . ftm am I the only one who is feeling this way ?!
