New and feeling down

Hi, so I am new here and I have been struggling of late.
I am 26 years old and have only recently been diagnosed with PsA.
I have been having symptoms since I was 24, and was only diagnosed about two months ago with PsA, I am now on Methotrexate (20mg once a week) folic acid (1 tablet once a week) and Suphasalazine (4x 500mg a day).

I have been with my husband for 8 years this year, and we are both wanting children, I am aware that I shouldn't fall pregnant while on methotrexate and that I should stop this for at least 3 months prior to conception, but I wanted to know if anyone has had problems falling pregnant after taking either of these drugs???

I already have concerns with my fertility and have been struggling lately with the thought of not being able to have kids of my own. For three years prior to me having symptoms, I had the Implanon in my arm as contraception, during those 3 years I didn't have a period, I had the implanon removed about a week prior to my symptoms starting, and about a month after that I started getting a period again, which I got regularly until earlier this year where I did not get a period for 3 months, all of a sudden it came back, up until about 3 weeks ago when I did not get my period as usual, this has been scaring me, and I know that I am definitely not pregnant now so I cant help but stress that I have fertility problems.

Does anyone know if PsA is linked with fertility problems in women?

thankyou!
Mel
