Help please! 🙏🙏

I had a very faint pink positive FR test last night at about 8pm.. I also had a herbal tea before the test and some water before bed.. my husband starts work in the middle of the night, and at 1:45am when he got up, I was up to and went and did a wee.. I then went back to bed and when waking, I took a test about 6:30am but this one was completely negative.. I later took another test 1.5hours later and was negative also.. does this mean I’m not pregnant or have had a chemical? Or could my nighttime wee have thrown everything out to give negatives in the morning?? Please help 🙏🙏🙏 I’m praying I may still be pregnant. 🙏🙏🙏
