Been doing a lot of research... :/

So I read some stuff bout how to naturally figure out if your fertile. Short periods can mean that your not ovulating..,, well my period is about 3days long. Normally light or spotting for the first n last day. Should I worry about this? Then I been looking into things to help fertility. Preseed or ovulation kits? Any recamedations?? Uhm trying to figure out if positions affect anything. I feel so lost in all of this. Thinking about trying so hard for something that I suppose to happen naturally. It's truly taking a bigger toll on me then expected. Been trying naturally with my husband for a year. Now that I'm trying the alternatives I feel I am losing hope.... I guess I just need someone to help me or idk...
