Unfortunately it didn't really answer. So how do I know what has caused the missed period?
I've never missed one before and I'm regular.

I'm also on lamictal and kepra but have been on these a long time before this has happened. Nothing new has happened between my last period and now.

At my last GP appt it showed that I had a low red blood cell count and low in iron, hence the folic acid. Could the folic acid not be working? I've been on it for a a couple of months.
Would appreciate more advice

Brief Answer:
iron deficiency anemia is causing irregular periods

Detailed Answer:
Hi back my dear,

I understand your concern.

Now, for a better understanding, I can say that iron deficiency anemia is causing your periods to delay.

Folic acid will help restore the low count of red blood cells without causing irregular periods.

Depending on the severity of the anemia (a copy of total blood count result will help me understand the current severity of anemia), it will take a while to resolve the problems with anemia and irregular periods consequently.

Hope it cleared up your doubts.

Hello, I noticed a few lumps in my groin where my leg meets my trunk while shaving about 9 months ago. They are painless and stationary, and have since spread and multiplied to all five lymph sites. I have had fatigue and extreme weight loss as well as unusually itchy skin. I also have several wart like bumps in my groin, chest, and neck, and no matter what I try they will not budge and have also multiplied. I have also noticed a few odd shaped, flat brown spots that are uneven.
what could this be? Thank you!

I have a concern regarding my periods. I don't have a bleed for a few months then I get what I think is a start of a period, usually old blood.
Recently every time I go to the loo I have a heavy bleed and then nothing again. This has been happening for a few days now. This morning I woke up bursting for a wee and I bleed slightly, later I went for a number 2 And I bled more heavily.

Could there be something wrong
