Too Much Sleep

Hello mommies, I'm 10 weeks pregnant & I sleep too much during the day (morning & afternoon). I feel so sleepy during the day then sa gabi nmn I can't sleep early so mga 12 ako natutulog. Nakakahigh blood ba ang too much sleeping sa mga buntis? Is really that bad? Sobrang antukin ko kc hnd ko mapigilan, bawal din ako mapagod or too much work kc I had a miscarriage last year so maingat ako ngayon na wag ma-stress.
