Question

So my periods have always been 5-7 days and getting lighter to a brown color by the last day or two well this last month we tried conceiving but I got my period again. My question is that is it possible that your period gets a little longer when you try to conceive if it fails? Because my period is still flowing like I’m in my first couple days of a normal cycle. I hope this makes sense but it’s just weird that all of a sudden my period is a little longer than usual as soon as I decided to try and conceive
