Period during pregnancy

I was wondering how many of you had your period still when you were pregnant? I counted myself out last month because AF came and stayed the normal amount of time then today (at 7 dpo) I tested even though I knew it was too early to be positive and in a matter of seconds I got a positive result so I tried a FRER and it became positive in a matter a seconds! I was in such disbelief. I went and got one of the tests that has the weeks estimator from ovulation and it came up with 2-3 weeks. Here is where my concern is, 2.5 weeks ago is when I had my last period so did i ovulate extremely early or extremely late. Anyone ever have a similar situation? Im just concerned that the weeks estimator should say I'm farther along based on glow's prediction of my ovulation and that I got my period while pregnant. I have a doctors appointment set for October 3rd but that's a long time to wait for me 😉
