Week and two day period?

Frances • I`m married, been trying to conceive over two years and still no luck.
Is that normal?
​I know I should know my periods...
​Yes there irragular ,
​March 24th I had light period for the whole two weeks.
​Then April 24th I was surprised it came at the same time like last month. Now it's been one week an two days... It's on and off but heavy & sometimes light. This month I tried something new with my husband and having intercourse TTC. It will stop while we do it and then goes back on after a few hours. Last night I got my old blood telling me it ended so we did it again & now it's back ok... I'm wondering if it's because of us having sex or something is wrong an I bleed for to long... Has anyone else have had long periods before?
