Should I be concerned?

Nicole

I have my period as normal then 2 weeks later it came back but much lighter than normal. No symptoms or anything like my normal cycle. Normally I have bad cramps, moody, heavy during days 2-3 then lighter and spotting during 4-5/6. This have never happened before. Shoukd I be concerned and go to my doctor? My husband and I have been married for just over 16 years and TTC for just as long (not actively).
