PCOS positive pregnancy test.

Nya

I was diagnosed with PCOS some years back and I was worried I wouldn't get pregnant. Last month, my husband and I tried again for a baby. I was on clomid from the 3rd day of my flow. And according to my calendar i was supposed to ovulate on the 16th of January. On the 29th of January, 4days after my period was supposed to start and 14DPO, I did several pregnancy tests and they were positive. I also took a blood test and hcg and those too were positive. I went to do an echography and nothing could be seen. Please was it cos it was too early?
