Implantation?

Livia

So I've had a horrible migraine the past few days, and I've had a lot of other symptoms of early pregnancy and I was going to take a test this weekend, but I started bleeding last night. It wasn't bad, but it raised alarm then I realized that it might be implantation bleeding. But I just woke up this morning and I'm bleeding more, and it's resembling a period but I'm not suppose to be on my period for another 2 weeks. What should I do?
