kimberlee is right. unprotected sex will eventually lead to pregnancy and you could very well be pregnant. get an hpt. it's the only way you're going to know for sure. we can all sit here and discuss symptoms but.....not everyone has the same symptoms. the only early pregnancy symptom i had was back aches. my big time symptoms didn't hit till i was 12 weeks. that's when the nausea, sore/swelling breasts, fatigue, frequent urination and crazy cravings started. others i know started at 4 weeks, 6 weeks or as late as 20 weeks. everyone is different. and don't forget a lot of early pregnancy symptoms are the same as pms.
the digital tests imo are the best. there's no confusing lines, pluses, negatives just a PREGNANT or NOT PREGNANT. you won't have to worry about evaporation lines or anything like that. they are a bit more expensive. the one i got was $13 for 2 tests. but definately worth the money. and if the last time you had unprotected sex was in february then it has been long enough and you'll be able to take the test now if you want.
Hmm, I had all the same symptoms as you, I kept feeling like I was going to get my period, I was feeling bloated, cramping, my nipples hurt, and everyday my period never came, then I started getting more discharge (white, or clearish, kind of lotiony feeling) and I'm now more than halfway through my pregnancy, so it's possible, and since you were having unprotected sex, yes it's possible. The continuous spotting though could be caused by your period trying to come, but waiting to see your period is going to delay it more, I'd say, wait about a week and test, if you can. And how are you so sure you don't have an infection?? That's one of the main causes of irregular spotting, so keep that in mind! If you aren't trying to get pregnant, you need to get a regular form of birth control. Unprotected sex will eventually lead to a pregnancy.
