Me and my husband have had unprotected sex 4 days before my period.. some of the cumulative came out but not all of it.. could I be pregnant?

Also I haven't had my birth control since Sunday

Yes you could.

I only have a 4 day period.. but when can I test and see what it will say?

Now I also have a milky white discharge

You will have to wait to see if you get your period next month.

OK thanks.. I'm hoping its positive because we are trying for a family
