Hi everyone, feeling confused can anyone with better grasp of biology help? I’m eight 1/2 months post Partum but my periods have not yet come back (breastfeeding). Stupidly had unprotected sex (first time since daughter was born) 23 days ago. I know there’s a chance I could have been ovulating so technically could be pregnant. This week I’ve been having sour taste in my mouth which for me was a strong symptom with both my daughter and my son (4). Says online you can test 21 days after sex but I’ve tested for the past two days and it’s negative. Would it be showing up by now if I was pregnant or not necessarily? Slightly panicking as very much not TTC….
