I need your advice please! Or just a comment!

So I'm getting really worried. Lately I've been having longer cycle 38,41,39 and I ovulated on all of them on time. This current cycle I ovulated on cd 16 and now it's currently cd 50!! Cramping off and on, very sleepy. I'm just so confused. Is there a chance I may have something wrong with me? Or is there still hope on getting a bfp? Tuesday I'm schedule for bloodwork. Been ttc for a year now and feel like I just took a huge step back 💔

Update: I do ovulation strips thru Amazon
