We had protected sex but he only put it in only once without a condom in between rounds on the 14th. My period was supposed to start on the 15th but when it was late I got worried, I have usually consistent periods. So on the 16th around 3pm I took plan B one step but my period still hasn't come and today is the 18th. I have mood swings, I'm bloated and my back aches, all signs of my period starting or in place but I'm not bleeding yet. I'm supper worried and anxious right now. I'm definitely on my own in this situation, please if anyone has anything to help me or settle my nerves?!
