"i started using the pill for the first time 3 months ago due to terrible cramps, periods every 3 weeks lasting 7 days, extreme mood swings, and just overall miserable, painful periods. when i started on sronyx i had nausea with mild headaches for the first couple of days. after that those symptoms went away. my periods still started on the 3rd week, so my periods lasted for 2 whole weeks. this happened for 3 months. i am switching to seasonique, because i need a heavier dosage. had sronyx been a little stronger it would have worked well. my cramps were much more bearable and the bleeding was less. overall it&#039;s a good pill, just not the one for me."
