I had sex with my boyfriend on the 7th October but the condom split so I took the morning after pill on the 9th. My periods are normally regular but it was meant to come on Friday and hasn't done yet. I feel extremely sick and dizzy, also unusually tired and very emotional. My breasts are slightly tender and I've had some cramps. I'm now worried I could be pregnant so has anyone else experienced the same thing in the past or think I could be? I'm going to the doctors later but just want other opinions before. Thanks for reading. I'd really appreciate any help...
