Ay, cramping with tingling can be normal sa pregnancy, pero kailangan mo talaga i-check with your OB para sure, some of us din nag-experience nito at okay lang, pero better safe than sorry lalo na if it's something new or getting worse! Paano ka na overall, any spotting or anything? I know ang dami ng confusing symptoms pag buntis, kaya importante talaga makausap ang doctor mo directly about the exact timing and location ng cramps mo.
