So my husband and I haven’t been on any type of birth control and we’ve been trying my period has been pretty inconsistent so that’s why I haven’t taken a pregnancy test but now I’ve gotten my “period” but it’s been really brown and stringy not too sure if I should still bother to take a pregnancy test since I’ve technically on my period can you still get a positive pregnancy test if you are bleeding really confused need opinions! ASAP thank you
