Period

My first period after a D&c was 36 days out. Then my second was exactly back to a normal 28 day cycle. I am currently on day 26 and waiting for my period to either show or I will test. I’m just wondering if it will be a 28 day cycle again or longer and I should wait a few more days to test for better results. Ugh I hate this ttc thing. I feel like since our loss it’s all I can think about. Even when I’m at work or out it’s still nagging in the back of my mind.
