Worried first time mum

I was due AF on Thursday 27th May and I’ve taken 3 pregnancy tests since. They’ve all been darker than the first, first one on Friday morning (5am) had a faint line, second one on Friday (about 4pm) was darker and then another on Saturday night (about 10pm) was darker still.

The doctor told me I may struggle to get pregnant so it has always been a worry for me.

I haven’t been able to ring the doctor to make an appointment yet as it’s bank holiday but I’ll be ringing them tomorrow.

I’ve been feeling nauseous, tired all the time and I’ve been getting intermittent cramping. Wouldn’t say it’s been severe cramping but more than I get during my period (I normally have one day of severe cramps and then next to nothing).

Does anyone think this is anything to worry about? How many tests have you guys done before you began to believe it might actually be real? 😂

Sorry for the really lengthy post!
