Hello, In normal women, sometimes period may become irregular. No need to worry if they have returned back in the usual way. As far as your fertility
is concerned, If there is no known problem with you or your husband, then it is better to wait for two years before u go to an expert for help as >90% of couples conceive within 2 years of marriage. If you as a couple have any problem then go to a good fertility clinic right away for full evaluation and help. Best wishes.
