Over weight , Labetalol while pregnant ?

I’m currently 11w6d I started to take Labetalol twice a day at 10w4d after my doctor changed it I was on norvasc.

But ever since I started the new pill I’ve been having non stop headaches, really sleepy, and feel really weak. I’ve been taking my blood pressure at home and it seems normal 120/77 - 128/73 but I just feel so weak and on top of that the headaches are so annoying/frustrating as I have a 2 year to take care of, been taking Tylenol for it. I was wondering if someone else has had these symptoms ? Could it be that my body is not used to it? I have an appointment on the 9th im bringing up to my obgyn. My doctor said to start baby aspirin at 12weeks. Maybe it make my headaches go away?
