Hi, Well I'm 17 and half years old. I think I started my period roughly on the 1st of June and finished roughly on the 9th. But I had sex on the 8th (saturday at 11 pm roughly) because my period was light and hardly there, we were protected and he didn't cum at all inside me, that's what he said. Anyways on Tuesday 10th at 8:30 am I took the plan b or morning after pill to be safe, I had no vomiting but I did get cramps and a light period(spotting) brownish/redish colour. Then it disappeared within a week. So finished about on the 18th.i took a pregnancy test it came up as a negative. Then a week and a half later I took another & it was negative. I still haven't got my period and I started being worried so I took another test on the 7th July and still negative. It's now the 11th of July and I still haven't got my period but this week I have been getting weird cramps (like when u work out at the gym and your muscles are sore) and feeling slightly nauseas. But no vomiting no period ? I'm confused. Am I pregnant? When will I get my next period? Please help! I can't be pregnant. I'm still at school at its worrying me sick.
