Advice? 10 days late

Hello!

I’m currently 10 day’s late. I take the mini pill religiously. A few weeks ago I had a UTI which had to be treated with antibiotics. My partner and I had sex on the last day with no pull out.

I took a test two days ago and saw a faint line. Since then I’ve been super nauseous, sore boobs, TMI constipation, gas..

I spotted lightly two days ago, only when wiping but nothing since.

Any advice ??
