Period / ovulation / chemical

Hello ladies so last month I had a chemical pregnancy. (got confirmed from my doctor) My period started 2 days early first two days it was a normal period and the last 3 days were spotting (barely anything there) long story short turned up as a chemical. So I'm here because I don't know if I did enough this month to get pregnant. My last period was supposed to come on the 19th of my but came the 17th. Do I go off my period that was supposed to come on the 19th or the 17th? This month it's says I ovulated on the 3rd but I got this snot looking stuff on the 4th

so I bd on the 4th. I bd on the 28,31st and 4th. Sorry if I sound all over the place. TIA SORRY FOR KEEP POSTING, BUT NOT REALLY GETTING ANY ANSWERS
