Cramps at 5weeks

Roland
Hi, today I'm 5 weeks 5 days according to <a href="https://play.google.com/store/apps/details?id=com.glow.android.nurture">nurture</a>. This morning at around 3 am I woke up with this bad cramping on my lower abdomen. I understand cramps are normal, but I guess it's nice to hear reassurance from other ppl experiencing it. I didn't have any bleeding, but the pain was so bad, it felt almost as if I was getting my period. Took 500mg Tylenol, and the discomfort went away. I was so afraid to go pee, afraid I would see blood in the toilet... I'm sure some of you might have had this feeling at some point?? When should I expect to have my first ultrasound and hear my baby's heart beat?  So excited and anxious at the same time..😁☺️
