I’m panicking😭

Guys i don’t know what wrong with me😭 i literally had a regular period last month, had a period this month but it was really weird and light which is so not normal for me, I’ve taken 2 tests since then, one a week after and one 2 weeks after, and I’m still scared that I’m pregnant😭 it’s all I can think about. I just feel so off! I’m also on a birth control pill (combo) and take it on time every single day. and i use protection with my S.O. Every time besides 2 and those were after my October period and I’m absolutely going crazy over this. Would a test show up positive by now since those unprotected times were at the beginning of last month? I thought i don’t ovulate since I’m on the pill and take it perfectly but could i still get pregnant?? I’m so scared and i feel nuts😭😭😭
