Hi. I'm on day 35 of my cycle without any sign of my period coming and pregnancy tests are negative. Usually I run between 28-32 day cycles, with one being 35 days several months ago. Basically, I started my period on 2/25 and was monitoring via ovulation test and 2 positives on 2/18 & 2/19 (days 21 & 22) and had sex both days.

Should a pregnancy test show up by now?
