Weird feeling at 6 weeks

So I had a weird feeling when I woke up today. It was like my stomach was tight and crampy and I needed a really good stretch. I wouldn’t say it was painful but it was worrisome considering my history. Has anyone else felt cramping at 6 weeks and went along to have a healthy pregnancy? I’m planning to go to the free clinic next week and really pray this sticks. I feel fine now just super moody all of a sudden. Today is not my day lol. Please send some positive energy my way!
