Coil removal and TTC

My periods have been very regular whilst on coil (28-30days).

On day 16 of my cycle I had the coil removed, day 18-23 bled very heavily bright red blood with period cramps, and now day 24-26 brown discharge.

Was this my period? Will my period still come in 4 days? Will this alter my ovulation?

We wanted to TTC mid December as I was due to ovulate then..
