Cramps now are feeling more like gas pains /upset stomach, instead of menstrual that I felt before. First ultrasound on the 23rd :)
It's ok to cramp just not really bad. If you aren't having bleeding then just try to relax and rest. The headache is from extra bloodflow going through your body. Your body is doing some tough work right now and you'll notice that you'll be extra tired as well.
Just take it easy.
Cramp is normal for me. I got cramp and tummyache since the beginning up until 18wks.
All my ultrasound come back perfect and the baby is healthy and kicking a lot.
As long as you're not bleeding or spoting you should be fine. As for the headache, it can be that you're not drinking enough water.
Call your doctor if your are still worry.
