Help please!

Ive been off birth control since the start if summer(2018) and me and my fiancé have been trying with no luck! We think I had a chemical pregnancy in November (my blood HCG never got above 10 and I had a normal period shortly after) I have attached pictures if my glow predictions and recent cycles, Im supposedly ovulating today and my CM is very watery but still stretches a bit between my fingers. I also had very light spotting on the 25th of March which would be cycle day 15. Ive had a couple symptoms such as nauseous, headache, mild cramps, frequently using the loo and a dry mouth and metallic taste. My cycle is just so messed up... it seems like the universe doesn’t want me to be a mommy 😔 ANY INSIGHT WOULD BE GREATLY APPRECIATED!!!!
