what's going on with me??

So a little back story. Ive been on birth control since I was 16, im now 27. Anyway I stopped taking my birth control at the end of March. I got my period like 10 days late but was happy it came at all. I know after being on birth control for awhile that things can get a little weird for a bit until your body regulates again. Well I've been taking ovulation tests for the past 5 days and nothing. No surge at all.. I plan on taking another one later this afternoon. I'm just nervous because according to this app this is my ovulation time and unfortunately it's been wrong. I'm getting a little stressed out. Has this happened to anyone else?? I'm just worried that what if I don't ovulate at all ya know? I'm dying for a baby and I know it's only been a month and a half of ttc but sometimes I can't help but be nervous about it. Id really appreciate any help or advice anyone could give me! Thanks!
