TTC and migraines - a herbal dilemma

[calicocat]

Hi everyone
I have a bit of a dilemma and was wondering if anyone might have any advice or experiences with ttc and migraines.
A friend recommended Natures Own PMS Essentials for migraines and since I've been taking it haven't had one, it's been brilliant! I was getting 2 or 3 a month.
However, I've been sussing out the ingredients and am now worried they just aren't compatible with ttc.
It contains black cohosh root and I've found some material about it suppressing the release of lutenizing hormone, thereby inhibiting ovulation.
Wonder if this might explain my 45 day cycle this past month
it also contains chaste tree fruit (vitex), winter cherry, B6 and a couple of other things.
Does anyone have any experience with this supplement or the ingredients?
I guess I'm going to have to ditch it.
Are there any alternatives that might be safe to take while ttc?

That doesn't sound good. Maybe ask a health food store.

I also get migraines. It was one a month which lasted 3 days, while I was on the pill. I wrongly assumed they would stop when I stopped taking the pill. Now I get them randomly throughout the month, but more so in the tww.

I'd be interested to see what others suggest
