It’s a mess

So basically, here’s my story..

I have previously had 5 miscarriages with my ex partner, we split, I met my now husband and decided to get the mirena coil until we were married and settled.

I was diagnosed with PCOS 3.5 years ago.

I then had the mirena removed in dec 2017 after 3 years. I had 3 regular periods which I ovulated and charted. Since then it’s gone crazy! I was 80 days late, for my period for 8 days, I’m now 20 days late and have been having period pains for about 2 weeks now. The pain is absolutely horrendous after sex, drove me to tears! I have taken 2 tests which were both negative and now I’m wondering what it could be!

I had a scan earlier this year to monitor my PCOS and nothing had changed..

Any advice be would be greatly appreciated!

Thank you in advance!
