Okay, I get my period every month on the 10th.
I never miss it and its neverrr late.
So in February I got my period on the 10th - 15th.
In March I had unprotective sex on the 7th.
I got my period on the 10th, but it ended on the 11th?

(I had an overian cyst so when I "got my period" on the 10th of march theny started me on a birth control to prevent me from getting the cyst, but im still supposed to get regular periods for another 3-4 months.)

Well now its April 14th..I still havent gotten my period and im alittle bit nervous.
Its been about five weeks since Ive had unprotective sex, I've very queezy (daily) I was throwing up last week alittle bit, but now im just queezy. My lower back is verryy sore. My boobs feel very sore and irated. I extremely tired, but I cant get to sleep at night (I toss and turn for hours) I go pee every five minutes (or atleast it feels that way haha) and from what my boyfriend and friends have been saying ive been having alot of mood swings. And I was spotting about a week after we had sex and i was spotting for about 6days on and off
Ive taken three pregnancy test and they've all been negative..but the symptoms are still there.


What do you think it is?
Or what should I do
