Scared?! Maybe over reacting? Help?!

I’m not sure where this should actually be posted I just need someone to tell me I’m not crazy. Or maybe confirm that I am. Idk. 😂 But I got my period last week. Or I thought. I had super bad cramps the first day and my back hurt like none other which is fairly normal. Only my period was light. The entire time. Like a light tampon was more than enough. Now I’m super emotional, my hips hurt. Which is kind of normal but it’s usually one or the other and with some stretching it lets up. Now it’s both, and I can’t sleep on my sides because of it. The only other way I can sleep is on my stomach and it feels...full? I’m not sure how to explain it. It’s different than feeling bloated. This morning I’m nauseas, and my legs and arms feel weak. I walked outside this morning and had to hold on to the rail because I got dizzy going down the steps. Which is not normal for me at all. I’m chalking it up to anxiety. Things have been kind of chaotic lately. But I still wonder because my bf and I don’t use condoms. He’s never came in me that I’m aware of but he waits until the second right before he comes to pull out. I think my minds just wandering. 😅
