I think I might be pregnant. I usually have regular periods although I had to use the emergency contraception pill back in feb and I don't know if that's the reason my periods have been odd. I had sex with my boyfriend about 10 weeks ago but used a condom. I had a period about a week later but it was only 2 and half weeks after the last one which was odd for me and .I have only just come on (which is about 2 months without one ) but its not as heavy as normal. I feel bloated and look bloated I feeling odd sometimes sick and have been getting headaches. Could I be pregnant and just have periods ?
