Af problems

Jenny

So this is my third cycle since getting off of depo last Jan. My first cycle consisted of 3 weeks of af that was crazy heavy and last 52 days total. My last cycle had 6 days of af that was medium and got lighter as the days went on. I used opks and got a positive and then had ovulation spotting. I was supposed to start af on the 23rd. Yesterday I started spotting and thought it was af. I had some light bleeding When I used the restroom this morning but otherwise I have only had a little spotting today. Is this af or Not? should I see my ob? I don't know what to think with this. I've been ttc since March with nothing :(
