Should I be worried

Hey beautiful ladies!

I am 30 years old 5'2" and about 225 lbs. I took my last BC pill on August 5 and had a withdrawal bleed 8/8-8/11

First real period 9/3-9/7

Period 10/7-10/11

Period 11/16- currently coming to an end.

My p tracker lte estimates my average cycle length to be 33 days.

My question is do you think my weight will prevent me from getting pregnant? Our first month of really trying was October and I felt so defeated. Af was 10 days late and my temps remained high but then fell and af showed. I know I ovulated late last cycle (around cycle day 30) and of course I was away for my sisters bachelorette party weekend so I guess having sex prior to leaving didn't do the trick. I am trying to eat as healthy as I can and lose weight but with the holidays coming I am so scared to gain. I've lost about 10 lbs in 2 months just by watching what I eat and I started working with a nutritionist.
