This is my 3rd month TTC. AF was 4 days late, but I had been feeling cramping for a past 2 days - so I knew it was coming. Today I woke up to a really heavy flow and some of the worst cramps I've ever had. My periods have been relatively mild as I've gotten older - they were this bad in my early teens. Anyone know why this period is worse than usual? Just seems strange to me. TIA!
