My menstruation cycle is not that regular sometimes is 28 cycle and sometimes not,last month I menstruate on 15-18 July on 02 August I and my boyfriend had unprotected sex 08 days after sexual intercourse I had my periods again which last for four days from 11-14 August but I was supposed to menstruate on the 15th so I could met my normal cycle now few days approximately 9 days after my periods I am now experiencing these problems morning time when I wake up I feel like vomiting but I will not vomit and I am having lot of saliva in my mouth, abdominal pain and sometimes headache. May I be pregnant?

There is only ONE way to know: a test. Buy HPTs in a drugstore (urine test), or go to a clinic for a blood test for more accuracy if the HPTs read negative.

Really early for those signs, perhaps more the flu??

Missing a period is normally the first sign.

So about 5 or 6 week after sex if no period try a home pregnancy test

Thanks a lot my people I think I was just afraid of being pregnant maybe
