Curious mama

So I have two girls. And my husband and I decided to try for our 3rd one. He’s hoping for that boy. Anywho I was on the Mirena IUD and I got it taken out March 22nd of this year. & got my period 2 days later. March 24th. It lasted it’s 5 usual days. After my period my app was telling me what days I was ovulating most. We went for it and had sex for 10 days straight. Just to make sure we really tried for a baby. Well as of yesterday I’ve been bleeding. Yesterday was a heavy day, mostly deep red and a little brown. & today right before I laid down I checked again & it was more of a brown.. I don’t remember this happening with my first two. Any mamas have any advice, opinions anything helps..
