Late period?

An

Hey guys! I have a late period along with the same symptoms I experienced with both my daughters when I was early pregnant, eg. nausea/food aversions, sensitive smell, sore/swollen boobs, fatigue, moodiness… but have tested 2 times, both in the afternoon (once was 2 days before missed period and second was on day 2 of missed period) and both were negative. My period is and always has been regular, so I’m unsure what could be causing it to be like this? My daughter is 3.5m old, and I’ve had my period since 6w pp (stopped bleeding at 5w pp). Has anyone experienced a negative pregnancy test that actually ended up being positive? There was a suuuuper faint line, but I gathered that it was an indent as didn’t get darker with the second test and was barely visible..

Pregnancy test is first response.
