Period advice please ladies

So me and my oh been trying to conceive for a year but last 4 months my cycles have only become regular ish ! We have been using opk but still not conceiving I’m starting to wonder if it me that’s causing for us not to conceive as my periods when they arrive are extremely heavy I have to wear 2 pads and also in agony ....

anyone shed some in light of weather they had this experienced and what happens from there ??

Before you start bashing I’m just asking other people experience I am going to go to the drs too !
