is this normal?:/

[Sophiehfz2805]

Basically its been around 2 and a half weeks since i gave birth to my DS as i had a miscarriage at 5 months. I've been bleeding since then which was the 29th of may. I've not been bleeding for around 2/3 days now and have started to TTC again. I had sex earlier and when i did i wasn't in pain but at the end it felt a bit sore/light burning feeling inside. Is that normal? Im guessing it is but then again im not sure so someone help please
