Trying to get pregnant for second time

Hi guys

Myself and my partner are trying to get pregnant for second time.

Our little girl was born in october 2018

Since then i had blood clots and now on blood thinners

Since we started trying properly in December i have noticed a distinct trouble getting it up.

Has any one has experienced using viagra been able to get pregnant ok.

I am worried im letting my partner down.

Did any one find natural ways of getting an erection as we a really desperate to get a second child and im worried its me it causing problems

Any advise with an erection or getting pregnant again and with keeping relaxed around it all.

Thanks
