is it too early to test?

feb 2016 I had my implanon taken out. may I was pregnant with my first (who didn't make it past 29 weeks). I was devastated. I was told by my maternity nurse to wait for 8 months after I gave birth to my premature baby in Jan 2017. it is now Sept and we have had sex on my 3 most fertile days and highest % chance of getting pregnant. I am going toilet more and getting random big juicy spots all over my body. my cervix is also high and soft. could I be pregnant? I think it's also to early to take a pregnancy test. when do I need to test?
