We are trying to conceive. This menstrual cycle I have been using ovulation tests and the test said I'm ovulating today, but my mikvah night isn't until tomorrow night (Shabbat) and I'm not sure what to do.

Another tricky thing is that the mikvah is a three mile walk from where I live and there's no eruv, and I don't know the area well but can't carry a map. I've never done the walk alone before but my husband is a resident and will be working.
