I’m too scared to check but need to know!

ar

My last period was in October 2017, we’re now in January 2018. Still no period. Significant weight gain, nausea, fatigue, back pains. The whole wazam. It’s been a couple months and even after noticing these drastic changes, im still so scared to find out. You see, my cycle is usually very predictable and regular, yet this suggests otherwise. I’d be the happiest to find out that I’m pregnant, don’t get me wrong. Problem is that I’m pretty sure I’ve been traumatized. My fiancé and I have tried and tried for about a year now and nothing was happening. It was negatives back to back. All I remember is being so upset and sad for the rest of the day if I’d seen a negative on a test. A part of me wants to know if I am, a part of me is really scared to see another negative. My partner and I kind of let it be after noticing all we were getting were negatives. We just figured it maybe wasn’t the right so we gave it up until further notice. Should I check??? 😥 before I’m in too deep.
