Someone pls help me calculate!!!

So my last period was march 23rd, I ovulated early and got a positive opk on CD 11 (April 2nd ) and ovulated on CD12 (April 3rd) I got my bfp on CD 23 (April 14th) I don’t know how many weeks I am I only had sex once which was April 2nd and conceived. If I go off my last period I’m less than what I am so i want to go off the day I conceived but it’s more because I ovulated early. Someone help please!!
