Period every two weeks?

[BirdieFriendReturns]

My periods are regular - cycle is 28 - 30 days.

For the first time ever I’m on again - I’m only on day 15 on my cycle and bleeding.

I am TTC and started taking Pregnacare vitamins last month and my period was 4 days late. I’ve read that people have reported Pregnacare messing up their cycles due to a very high level of vitamin B6.

I’m not TTC but also suddenly had cycles of 14 days, then 21 days for first time ever, during lockdown (usually 28 days) and wonder if it’s caused by stress. Sometimes, though, an extra bleed can be caused by v early miscarriage. I didn’t know about the link with B6. I haven’t been taking my vitamins regularly.
