Is it possible to be pregnant without any early signs of pregnancy?
Yes, it is possible to be pregnant and have no signs of pregnancy. Many women *never* have any breast changes, nausea, etc. at any time during pregnancy. As for when in your cycle you can get pregnant, it matters not at all how long it’s been since your previous period. What matters is how long it is before your *next* period. A woman ovulates about 2 weeks (usually 12-16 days) before her *next* period. However, it is possible that any particular cycle is longer than your usual one (even if you are normally very regular). So, if you have a 35 day cycle, you will probably ovulate between days 19 and 23.
