I need help

AF was suppose to get here today according to my Premom app. I took a test this morning it was negative I have irregular cycles rang of 48-61 days ever since I had my child which is turning 5 in January. I have tried birth control to regulate but didn’t work. I have been TTC since November 2020. I have been tracking everything but I believe I am having trouble ovulating no luck and this cycle did not ovulate. Past couple months been very unhappy with myself because I cannot conceive and have been taking it out on my partner I feel terrible. Does anyone gone through this on there journey and have successfully conceived? If so any advice?
