Help please😩

I need you girls help, so I’ve been on BC for a year going on 2 years and I take it faithfully everything & i have been with the same person my boyfriend no we don’t use condoms but he does pull out. Yes! I’m aware of pre cum and all of that. But my period is suppose to start Thursday normally sometimes fridays and It feel like it’s coming I’ve been so irritated lately not wanting to eat. I also been kinda stressed lately losing my job not having money so my anxiety with everything is through the roof. No I don’t feel sick or anything & I barely eat now because of stress. I took a pregnancy test lastnight it was negative and one this morning it was negative so wth is going on! Should I worry?l
