Spotting during ovulation ???

I have a question and to anyone who might have some advice you are welcome. I am ovulating this week and two days ago was my very fertile day and I had intercourse with my husband and the next day I started lightly spotting but it was brown discharge and today it's become medium spotting and I'm a bit freaked out because it's only brown and I recently visited my family in a different state and I was wondering if that could have made a difference to my cycle at all I had a miscarriage last year in November and it wasn't the best of times and now we are trying again and I'm just really freaked out about the whole brown discharge....please give advice to a newb thank you!
