Advice needed please! MRI On Monday & Worried Incase Pregnant.

My cycle ranges from

28-34 days, with last month being 28 days.

I have been taking conceive plus tablets for the first time this month.

2 days ago I was having cramps like my period was coming and I kept wiping as I was sure my

Period was coming. I took a digital

Test and it was negative.

Yesterday I had nothing and no pains.

Today I woke up and did another digital and it was negative

Still NO sign of AF and all

Cramps have gone.

I am worried as I have an MRI booked for Monday and they asked if I was pregnant as I couldn’t have it other wise.

I don’t want to cancel the scan as waited for ages but equally what if I am?

Is there a possibility even though Tests are negative?

I have only done clear blue digital.

Sorry for the long winded message in advance
