Okay so I know I wrote about this in December but I have new INFO, On December 15th, 16th and 17th my boyfriend was in town and we had sex more then once with out a condom all three nights, well I was suppose to start my cycle on the 17th of December but it never came until the 23rd, the cycle I had was not as heavy as I usually get it and my cycle length is usually 25-28 days but this one was 33 days, on my period tracker (which is sometimes not accurate) says my ovulating days were Dec 9th and Jan 7th, I have been experiencing small little pains in my stomach and little cramps here and there since I've been late, my breast hurt and I get nausea here and there, I asked my boyfriend if he came inside me he said he's not sure because he remembers pulling out but he didn't see his anywhere not on the bed or on him or me so he has no idea where it disappeared... Now I am kind of worried that I might be pregnant but not sure someone help please.

Very likely,
Pulling out, where do you all get this silly information?
It does not work, there are plenty of sperm in the early fluids so if he went in, you got sperm in you.

It is not the time of the period, since it is common for periods to be late sometimes, early other times, so that is just something that happens.

But if it was not a full period, if it was much lighter and did not last as long, that is a sign of possible pregnancy.

It should be time to do a pregnancy test now.
Do it first thing in the morning with the first urine of the day.
Let us know
