Uy first time, paglilihi usually kicks in around weeks 5-6 ng pregnancy, pero honestly sa amin it was more like weeks 8-9 kaya huwag mag-alala kung late ka pa! Common signs are morning sickness (though hindi lang umaga talaga, buong araw pwedeng pakiramdam mo), sudden food aversions or cravings, and feeling queasy especially pag gutom or may strong smell, one of my mum friends said she couldn't even stand the smell ng kanyang favorite rice cooker kaya alam namin agad haha. Some moms barely experience it while iba talaga super sirang-sira, so if you're not having it yet or it's mild, that's totally normal too!
