What is wrong with me😔

I follow two period apps to ensure that i am up to date with my cycles,

My last period started on the 21st of October and lasted for 8 days. I usually have irregular periods but have been having regular for the past 3 months.

I also have PCOS.

I last had unprotected sex on the 5th, 7th, 13, 14, 16 and 17 of this month.

eve tells me my ovulation days were from the 6-12 of this month, i took a pregnancy test on the 18th and it came negative. According to eve i am also due my periods in three days.

My second period app tells me that i am not meant to be getting a period this month and that my ovulation days are from the 15-28 of this month. As i mentioned that i did have unprotected sex 14 and 16.

I am currently having headaches and bloatings with very harsh mood swings. Im not afraid of being pregnant but i just would rather know what is going on with me than suffer on my own not knowing what to do. I am currently the verge of having a mental breakdown as i dont know who to talk to😢😣😖

Took this test today can’t tell if i see anything or not!
