my husband and i had sex about a week ago i started spotting about 5 days before i was supposed to get my period.then next day was light bleeding kinda pink to spotting and then the third day was spotting once again i also had cramps along with this and nauseas and breast hurt im not spotting anymore but i feel extremly bloated and really tired im also as i mentioned nauseas and still feel a bit crampy and im starting to get frequent headaches although i am no longer bleeding could this be a sign that i could be pregnant and if so how long should i wait to take a pregnancy test? Also has anyone here experience these symptoms and turned out to be pregnant?
