I'm a little concerned :(

I have no idea what is going on with me . All I can figure is something with my blood sugar ! I've had problems with my sugar for a while now normally it'll just get to low, we'll here recently like within the past few days I can't keep it stable , it's always dropping and then I'll eat and it'll shoot up ! It could be a number of things number one I'm breast feeding my ten month old but he's Sorry hit send before I finished. I wasn't even alone with Mark.  His sister and her friends were with us I just wanted you to make you believe something different. I've asked him to reach out to you too. If there was something between us I certainly wouldn't ask him to contact you!!! weaning himself and not eating as often and I've never had this problem before until now . Number two my sleep cycles are so out of control I've been having such a difficult time going to bed at night ! Number three I'm going on two weeks late , I haven't test because I'm waiting to see if I'm two weeks late first ! Idk if I could be pregnant I was diabetic while pregnant with my son and maybe if I'm pregnant now my body is just having a hard time because I'm BF and my body is needing all of the extra energy .. Not to mention the nutrients I need ! Maybe my body just can't keep up :/ idk . It's worrying me ! Any ideas? I know I need to go to the doctor ! Another thing everytime I nurse and my milk lets down I get naseous .
