Possibly Pregnant?

**Long Post Alert**

Ok so to begin my cycle has been irregular ever since I've started having them. After about hitting my 20s it got on track and I'm now 23. after my miscarriage a year ago it's been downhill since. Moving forward i now track my cycle using several apps 4 different apps including this, and believe it or not they all say I begin a different date several days or even a week apart, while one just straight up say it's unpredictable 😂 mind you all the same information is entered 🙄🤦🏽‍♀️. Anywho.... according to one of my other apps that tends to be a bit more closer to my cycle (this is still a good app cause it doesn't have the bonuses for example speaking with you guys 😋) I ovulated through 7-13 this month with the 12th being the main day.

My partner and I had unprotected sex on the 10th using the pull out method, and i do not use any other forms of contraceptives. We did have sex again on the 16th. On the 21st and 22nd I woke up to light pink spotting which did not return throughout the rest of the day. This was 5-4 days baf was due to arrive. Again on the 24th I spotted which was light pink and disappeared after an hour.

As of today I am 5 days late and around 2pm after getting home from work I spotted dark reddish brown which actually came on my underwear but just a spot. Guessing that it was most likely here I used a tampon and after about 4 hours there was just a spot of dark brown blood at the very top. I haven't used anything else And still no sign of the spotting when I wipe.

To add my last cycle was 15 days late and lasted only 3 days which was 29,30,31 of July. Honestly my cycle is all over the place that I now expect af to arrive no later than 15 days.

I know I should take a test but somehow I feel it will be negative and kinda want to wait it out a bit

BUT Did any of you ladies have any similar symptoms and did get a positive result?
