Trying to conceive?

Ive had a miscarriage 17th November, I had bad cramps went hospital to check& they said I had a chemical pregnancy. So the days went on I was only bleeding for about a week. So, I thought I’d be ready to start again - I started to ovulate 23rd November , I had unprotected sex on 4 occasions, I am currently now finishing my ovulation when’s best time to take a pregnancy test?
