pregnant?

sooo the last time i had sex with my boyfriend was about 2 months ago, over the course of these 2 months ive experienced some weird phases w & within my body. in january & feb i had my period but they were actually really short & not as heavy as usual. 2 weeks or so ago i was discharging a lott everyday. i been feeling sick at time (nauseous, light headed) im kind of worried, i mean he says he pulled out & whatnot but there is precum. so im kinda on the edge whether to tell him if it might be something real or if i should just wait it off & see what happens this next period around. Oh yeah im supposed to start my period in a few days & i usually have cramps & boob pains a few days before i start & i have barley felt anything. im kinda starting to worry. someone please lmk what they think 😩😩  but ive been thinking maybe its just my body responding to such a sudden change, me becoming sexually active. im not really sure tho :(
