Getting depressed while TTC

Been TTC for about a month now after stopping the pill. Been tracking my cycle on a few different apps and with ovulation tests. I have taken 2 ovulation tests and both have come back as low. Based off the apps i use i am in my fertile window & today was supposed to be my peak day but ovulation test says different i guess :( My boyfriend never wanted more kids but he changed his mind and told me to stop taking my pill & i was happy! This would be our 1st "ours" baby! I will keep trying no matter what as i want at least 1 more kid! I have a son from a previous relationship.
