hahh ok Scherzy pretty much everyone has gained weight these 15 days due to general lockdown
.so the chart you posted last time was the day after you had sex and now this second one is after 15 days only have passed? is your period late? i told you back then that the chart wasn't indicative for a pregnancy, the negative testimonies were more.
Anyway we don't do multiple charts on the same question, this is one basic rule.
Still if indeed your period is late why don't you do a proper exam, going to a doctor and having a test, instead of asking multiple horary questions?
