Cervical Ectropion (Erosion)

10 days ago I had Silver Nitrate treatment on my cervix for an cervical erosion (due to taking the pill). I had cramp and discharge/bleeding on the first day and then just discharge/bleeding the second day then nothing. 

I asked the doctor how long to wait before sex she said 5-7 days. We waited 8 days but when we started having sex it was too sore and we stopped. Since then I have had period like bleeding.

Is this normal? I’m concerned it’s not.
