possible infertility?

I am not sure how to even start. My husband and I have been trying for a baby for almost a year. When I say trying I mean if it happens it happens. As of October 13th it will be one full year since I stopped taking my birth control. Well my period was irregular for about 4-5 months then it was regular after that. I would have a 25 day cycle with a 5 day period. Well since July I have been having issues. In July my period was a week late. Then it came and it was almost a 10 day period. Then August it was normal, now ta September and I got my period on the 25 days but two days after my period my husband and i bd'd and then I began to spot for two days. Then 6 days after I finished my period we bd'd and I began to have a period. I thought it was just spotting but it definitely isn't.  Also I took ovulation a tests and everyone of them for a week and a half were all negative. I would take them when I first woke up. Is that the right way to use them?Anyone else have this same issue?! I have an appointment with my OB on the one year make of trying. Any other suggestions?
