Results came back normal but I'm having irregular periods?!

I'm 22yrs old and my husband and I are trying to conceive (My husband and I have had unprotected sex for the last 2 1/2yrs). I've been using Glow to help me with keeping track of my Ovulation. 
​Last year I had my period in March and didn't have another period until October. I assumed it was pretty normal only because my husband proposed last February and the wedding was in October so I thought for sure it was just stress. Well I didn't get another period until this past February. The last 3 months I have been regular so I'm not 100% sure whether I'll get a period this month. I went to the OBGYN last Friday and had a Pap Smear done along with Blood & Thyroid testing done and all three came back completely normal. I take Gummy Vitamins as well as Prenatal Gummies daily. What is y'all's input on this? Thank you in advance!
