Fast pulse??!please advice

I know with pregnancy your pulse is going to be elevated. But lately ive felt dizzy on and off throughout the day. Ive taken my bp and its fine but my pulse was 130. I know thats slightly high but i honestly do not know what to do. I had my appt yesyerday and mentioned it to my ob and im supposed to have blood work done on friday as well as collect my urine for 24 hrs. She said if it keeps happening to call L&D and ill have to go into the hospital. I have my 3 yr old with me and my 7 year old is school ubtil 1245. My husband is 2hrs away at work, i have family close by but arent on speaking terms and im hibking of just waiting u til my husband gets home around 4pm. All i can do is lay down for a bit and wait until i feel a little bit better but idl if i should wait or keep checking my bp throughout the day and thencall? Please any advice will be appreciated.im almost 36 weeks if that helps
