Super winded and tired

Kjirsten • 2 babies in heaven, one rainbow, now 7, and 4yr old twins.
I am 10 weeks and 3 days and I feel like I weigh 700 lbs or something... I get so winded and tired so easily... Is anyone else feeling like this? I feel like I can barely do anything in full without having to rest. Thank god I have a desk job.
