Hi there.. My husband and i had unprotected contact last August 10. My last period was July 30-August 2.. Freakin' out cause that time i think inwas fertile and my hubby told me that it was withdrawn, but i am still worried. After being paranoid, i read about Nordette and took 4 of it on August 13 - 3days after unprotected contact. After 12 hours, i took another 4 pills. Suring the first dose, nausea and vomiting are the ones i experienced, though i did not vomit. On the second dose, i really had serious nausea and stomach upset, frequent urination, sleepiness, and feeling tired. Until now, i still feel nauseous and sleepy, also occasional headaches. My question is that, am i at risk atgetting pregnant? Am really confused right now, my hibby is an OFW and will be leaving for work again next week. Also, i read about withdrawal bleeding, will i have that also and when? Please someone reply and thank you so much! Lotsa love!!
