IUD & Pregancy. HELP!

Hello, I’m new here.

I had the IUD placed two months ago. I had it checked a month ago it was in the correct position.

For the last week I’ve been having pregnancy symptoms. Fatigued, mood swings, hungrier than normal and heartburn.

This is the second time having a mirena placed I had one last year and it fell out.

I have checked for my strings they are still in place yet hard to find they are like just there.

Moving on to Monday night this week, I had my first faint positive.

Come Friday I’ve taken about twenty tests which are all positive with a faint line.

Do you think these are positive or evaporation lines?

I also had an ectopic last year. I’ve read that being pregnant with and IUD can increase the risk of ectopic ?!

I had blood drawn two days ago and yesterday both came back negative with HCG of 2.

Help does anyone have advice or has fallen pregnant on the mirena ?
