5 Weeks Pregnant and Have Severe Cramps and Some Bleeding(varies Differently)

Cramping is normal. What you're most likely feeling is the round ligament around your uterus stretching, as your uterus starts to grow for the baby. It's 100% normal, and it only on one side...which can lead you to believe that it's in your tubes. It's very likely not, especially if you've already had an ultrasound. You'll continue to feel this throughout your pregnancy as the baby grows, BTW. You'll just be more clear about what the pain is as you get further along.

For the bleeding, it's also normal...or not. I bled with my first.
At the time, all the doctor can tell you is that there is nothing you can do to stop a miscarriage. You're either going to or not.
If the bleeding and cramping has already stopped, that's a very good sign and you're probably fine. The bleeding was likely from the ultrasound.

See what the doctor says.

Sounds like. Miscarriage from my personal issues. I am sorry!

could be, but also could be round ligaments stretching. See what the doctor says and good luck.

I had cramps for the first couple months of this pregnancy, but no bleeding. The doc told me at the first transvaginal ultrasound that there may be some bleeding, I just never experienced it. I had one ultrasound at 5 weeks, they couldn't see the baby and said it was too small, and they repeated at 8 weeks and could clearly see the tiny little embryo. I am currently 22 weeks along, and so far so good.
Can't say for sure until you see the doctor, but thought I'd share my experience. Good luck, I hope everything is ok.

I had bleeding and cramps for three months. Healthy baby boy born!!
