conception after iud?

I had my mirena removed on the 25th to try and conceive, I even took misoprostol or whatever to open my cervix for removal and had sex the next day and the day after that. I know my period is supposed to come in 3 days time, but if I did happen to conceive (yes I know its too early), would I still get my period or would I miss it? and when would a test seem appropriate? my first pregnancy I was on the pill for 5 months before my period stopped, found out I was 19 weeks 4 days.
