First pregnancy

Hi I'm belinda im 28 years old just found out recently im pregnant 4 weeks and 4 days according to my lmp very very excited. This is my first pregnancy but im always concerned. As i had pcos but they were boardline last time i checked. Ive been getting cramps for the last 4 days no bleeding just light to moderate craps on and off. I dont know if it just the uteurs expanding or uterus flipping as i have a retroverted uterus. I have a date scan in 2 days cant wait for that but i cannot wait for the first trimester to be over so i can worry a little less. I try not to worry and take it day by day but its always in the back of my head. BUT FIRST BABY arhhhhhh. Been waiting so long for this as i have tried for so many years 😊
