So, I'm not sure if I'm imagining it but I feel like something is wrong.

The last 3 nights I've had really strong cramping that wakes me up and includes lower back pain. It only lasts for a few minutes and then goes away. I haven't had any spotting or anything....yet.

I also feel like any symptoms I might have had I don't feel like I have them any more. Yesterday my nipples were sore, today they aren't. I felt like I had to pee frequently, right now I feel like I don't. I haven't been showing much for symptoms so maybe these aren't a big deal but I kind of just feel like something's wrong and I might be having a miscarriage?

If anyone might know what this sounds like, I would love to hear about it. Thanks.
