Early pregnancy symptoms

Sadie
So after 2 years of trying I recently found out I am pregnant. Doctor said I am between 3-4 weeks based on my blood work levels. (hCg= 250 and progesterone= 19.9)
When I was pregnant with my daughter my pregnancy symptoms where very mild until 6 weeks. That's when major morning sickness came on. I am 3-4 weeks and I have already got major all day morning sickness, my boobs are huge/hurt and I can't sleep worth beans at night. I'm just tossing and turning unable to find a comfy position. I lay on my tummy and the pressure in my pelvis is very uncomfortable. I know every pregnancy is different but I have a suspicion I might by carrying twins. 
Anyone experience strong very early pregnancy symptoms? And if so did you have multiples?? Twins run in my family 😊
