Is there something wrong with me?

My husband and I have been TTC for about 3 months now and still no luck. I just ended my period yesterday and I’ve had mild consistent cramps all day! I don’t know if there’s something wrong. I’m asking for opinions. And of course, if this is going on tomorrow as well, I will be calling my doctor. I just like hearing other people’s opinions or if any of you have some natural ways to make the cramping go away. Thanks!
