Hello! My husband and I are currently TTC. We have two daughters already from previous relationships and are hoping to have one of our own. We have been very mindful of ovulation days. Since Sunday I have been feeling what seems to be morning sickness (I never had it with my first) and it lasts about a half an hour then goes away. I’ve been testing everyday but it’s negative and I’ve need <a href="https://play.google.com/store/apps/details?id=com.glow.android">tracking ovulation</a> and it shows low ovulation. Is that a pretty definitive way to know you’re not pregnant! TIA for any help.
