Advice

So I had my period as usual then a few days later started spotting. I am 34 with a 9 year old and 10 year old. I am TTC with my fiance and we have been trying for 10 months. Then after spotting a few days...nothing. so then maybe 2 days later spotting again. Now after intercourse I'm bleeding like a normal period. This has been almost 2 weeks of bleeding. What is going on? Any advice?
