Sooooo scared

Went to a women’s clinic Thursday and found out I am 7 weeks pregnant and even got to listen the heartbeat. Best day of my life so far 💗

But Friday late afternoon, I started feeling very mild cramps in my lower abdomen and some back aches.. but no bleed of any kind. this is my first pregnancy and I am scared so much. I’ve googled it and read what feels like every web site. I could either be having a miscarriage or it’s just my uterus expanding or harmonies but I cannot take my mind off it. 😔😣
