i have "my calendar" it has period and ovulation tracking. is it the same thing?

my daughter is 20mos as well and we just started trying. I downloaded Ovia fertility and it's amazing!! I also ordered 50 ovulation test and 20 pregnancy tests off amazon for 17$ to check that the app is correct. and I've been taking prenatals for a few weeks

i love vitamens but they actually make me dizzy. like bad dizzy. and my period is due in like 2 days but last cycle was 80 days. it was crazy i thought i was pregnant. and have only ever had a 36 day cycle(after having my son). i dont really want to spend a fortune on OPKs. so what are other ways to track ovulation

both of u should start taking vitamins. tracking ur period and ovulation. that's what we did.
