Need to vent. Late period.

So I just got my first period at 6m pp on aug 20 literally back on track for what my fit bit says would be my period if I hadn't even had a baby lol so... I'm never late unless I'm pregnant (3babies). I'm breastfeeding no supplementing. I'm currently 5days late 😳. I had sex once since my last period 4 days after my "fertile" window according to glow. I know ovulation can be anywhere from 14-17days. He pulled out. I'm nauseous and exhausted. I had major headaches last weekend dizziness and seeing stars lol and felt all kinds of period like symptoms cramps back pain etc for a few days but it never showed. I feel like I want to accept the fact I should take a test and then again I'm thinking ehh maybe it's just stress. We had painters come last week, virtual learning, adding a extra child to the virtual learning at my house soon etc.

Ahhhh I just needed to vent. I feel like the possibility of me being preg is slim to none but my symptoms are like ehhhh you should test.

We were done at 3 but the pandemic hit so he couldn't get his vasectomy, I can't get my hysterectomy til next summer, can't take BC for underlying conditions, I know pulling out isn't fool proof, we moved in June and he hasn't found a Dr here and he is active duty but 1hr from base been super busy with home improvements. I would love to have one more. Deep down I hope it happened and don't at the same time lol
