I and my gf had made out on 7th of February 2018 and it was mainly dry humping and she had even washed her hands before going to the loo as I had got wet, so we are almost sure that nothing relating to pregnancy might pop up. She has irregular periods but has taken 3 pregnancy tests on 26th February 2018, 3rd March 2018 and 10th March 2018 all of which have been negative. But she still hasn’t got her periods. Also her last periods were on 20th January 2018, can we trust the
pregnancy test.?
