Help please

So I had my period from April 22-27 and those last few days I had a really bad headache, dizziness, somewhat blurred vision, indigestion more than usual. I wear a patch which I know isn’t the best birth control but it was the only one I was okay with at the time. Anyways so those symptoms lasted a few days after my period. And now I swear I feel something moving in my stomach. I do feel phantom kicks from my last pregnancy sometimes but this seems like more. So to get to the point.. how possible is it to have your period while pregnant?? Especially if you feel kicks a week after.😭 or can you feel something like that in your stomach and be like a condition or something? I know I probably sound crazy but I have 2 kids already and I’m scared. I have a doctor’s appointment next week because I was gonna get blood work or something done to see why I was having such bad dizziness so I figured I’d just get a test then. But if anything I just wanted to talk to someone about this because I don’t really have someone that I could talk to about this..
