I would think it would be your weight gain/loss that had more of an impact on your cycles than the prenatals.  My prenatals are literally identical to the multivitamin that I used to take (the only difference is more folic acid in the prenatal) and I’m like you- 28 day cycles all the time.  I switched from the multi to the prenatal and noticed zero difference. 

There’s a lot of information out there about your weight and how it affects your fertility- I don’t know how tall/short you are, but I’m 5’4 and 10 lbs would be a LOT of weight on me.  I can’t imagine how that wouldn’t totally affect every function of my body if I gained 10 lbs. 

You could always try taking a different prenatal, but for now, I would just take a multivitamin until you’re pregnant.  My doctor told me that because the extra folic acid aids in fetal development, until you’re actually pregnant it’s better to just take the multivitamin because most times the prenatals don’t have enough iron in them.

You can always get extra folic acid by adding in extra leafy greens- that’s what I do 🙂

I takeuse take One A Day Women’s vitamins, although I have to take them after I eat or they make me feel sick :(. I’ve heard the adult gummy multis are good too.

Something I started doing is making green smoothies in the morning- one cup of milk, two big handfuls of fresh spinach, a banana and spoonful of peanut butter. Sometimes I toss some plain Greek yogurt in there as well. It helps me get in some fruits and veggies, because I never feel like I get enough in the day, and it’s really yummy! Plus, you get all that good folio acid in the spinach :).

Did your pre-natals contain higher amounts of vitamin B6 or any fertility herbs or evening primrose oil? Vitamin B6 is commonly used to lengthen the LP and EPO and some fertility herbs can have an effect on your cycles as well.

Theoretically your LP should be fairly stable however over the course of the twelve months immediately after I stopped taking the Pill mine did go from ten to twelve days.

For vitamins, I recommend the New Chapter Perfect Prenatal. They are organic food-based vitamins, have probiotics for easy digestion, and the daily dose is split into 3 pills to be both easier on the stomach and for better absorption of nutrients (some nutrients your body can only absorb so much of at once). Also there’s no artificial dyes.


You need to be taking prenatals BEFORE you’re pregnant, if you wait until you find out you’re pregnant, you can easily already be past the point where extra folic acid does the most good.

My OB/GYN told me to take prenatals at least 3 months before TTC, and that I could start on them immediately if I wanted (this was when I asked her what I needed to do if we wanted to TTC the next year).

If you’re worried about getting enough iron, you can take an extra iron pill.
