Is it time to have fertility testing???

Just after some advice, we started trying to conceive April 2016, came off the microgynon pill, had treatment for abnormal cells on my cervix in the March 2016 which I'm now clear of. Sometimes I can have pain during sex when it feels like deep penetration, I've had this since I was first sexually actively, my Periods have been 29 days for the majority, had 2 occasions where they were 36 days long, I've recently started using OPKs got a positive pregnancy test at the end of November which resulted in a chemical pregnancy, we tried again straight away as my period was normal, and doctor said it's fairly common to have a chemical. I tested positive with opk around 14th December but whilst on holiday in Spain I had ewcm on the 27th, no opks to test so made sure we BD'd, my period was then late due 30th Dec all negative pregnancy tests from then until I got my period after 41 days (started yesterday) Did I ovulate twice? Would it be to soon to go to get fertility tests as it hasn't been a year yet? I just have a feeling something is wrong. Getting married next August and really want our baby to arrive  this year... 😞
