did prenatals mess with your cycle?

I haven’t noticed any difference at all, but then again I’ve taken multiviatimins off and on for years.

I’ve been taking prenatals for over a year, and multivitamins before that, and my cycles have always very constant.

Did you ever track your cycle before starting the prenatal vitamins? It is highly unlikely that any vitamin would affect your cycle in any way, provided that you were adequately nourished before (of course, not taking in enough calories can cause amenorrhea). If you intend to TTC, either track your cycle to see how regular you are, or use ovulation predictor kits. Our memories are notoriously unreliable when it comes to things like the regularity of our cycles, and tracking it and writing it down is the only way to know for sure.

People often like to attribute their ‘changes in regularity’ to one thing or another but really, they are just speculating because so many things (including things we can’t control, like age) contribute to changes in cycle regularity. I find that often people say ‘I’ve always had a regular cycle’ but what they mean is the last 4 cycles they’ve been tracking had similar features and before that they were on a hormonal birh control which regulates cycle length. it’s not a very long period to Observe patterns in cycles.

I don’t think that prenatals can honestly have any effect on your cycle. I would suspect that your co-worker’s wife might have been on hormonal birth control prior to TTC, which is what caused her cycles to seem “normal” before.

As for your own cycles, it’s very normal to have a 28 day cycle one month followed by a 32 day cycle or a 26 day cycle, etc.

Yeah to be 100% fair the inconsistencies is probably just because you are being more aware of it or stressed (even if you don’t realise). I’ve been on pre-natals for over 2 years (TTC for 20-21 cycles) and OTHER things have affected me like illness and stress but I can’t say I’ve noticed a difference since the prenatals (and I was taking them prior to TTC). Even now if I wasn’t tracking I wouldn’t know how long AF was or when she was due and often have to look back on FF to check up. So yeah if prior to TTC I had a crazy cycle (late, or longer etc) I wouldn’t have given it much of a passing thought. Not saying that SHE couldn’t attribute it to them but I would guess she might be an exception not the rule. 🙂

There’s nothing in vitamins that could do any of that. It’s more likely that she went on prenatals when she went off the pill, trying to get pregnant.

I’ve been taking them for over a year now and I haven’t noticed any changes except that my hair dresser said my hair looks AMAZING now and it’s super healthy.

I’ve been on them for a year and a half now, no changes for me. I have perfectly regular cycles, like clockwork.

I’ve been tracking my cycle for two years now while NOT on the pill and have just started prenatals a few months ago. my clockwork, 27 day cycles went to all of a sudden 32+ days! Idk if it’s the prenatals or not, but I’m not stressed or sick and can’t think of any other changes. I know people take B vitamins to lengthen their LP, maybe some prenatals have more B vitamins? Idk. But I’m 7 days “late” now and it’s pissing me off!! Lol
