Help please

So I’ve been feeling sick like super nauseous today. I haven’t had a period in about 2 months. I’m on birth control and my “periods” are inconsistent and they are basically splotting for a few days like a normal one would be. Idk if my body is still getting used to it. I used to have super heavy periods and they have been super inconsistent since. Like they will appear in the middle of the bc cycle or something. But I have sex with my bf he doesn’t ever come in me. Sometimes we do it raw and sometimes we use protection. Could I be pregnant? Just as a fair warning I’ve been really stressed out lately as well for a month or so.
