feel off today

Lovemylife • Mom to two awesome girls. 1 MC. Had my rainbow baby boy 6/5/2017!!!! So in love 😍
Idk what it is. I felt great yesterday. Took dog for a good walk and kids rode scooter. Then we went out to lunch then Walmart then walked the zoo for almost 3 hrs (it took 3 hrs bc I kept sitting down). N yesterday kids woke me up super early. Today kids left me alone I slept on a little bit (830) and I feel so off. I just want a nap. I have eaten three times n I still feel hungry. I feel weak. Ugh. Idk what's going on and why yesterday was so great and today I feel like crap. Hope all is ok. Always feels so long in between appts.
