Hey I'm always on the 7th and this month I started on the 9th. My fiancé and I have slept together since last month. He always comes inside me. The past week and a half I have slept with him everyday with him coming inside me. We already have one kid who is 10 months old. I took a pregnant. Test but it came back negative. What's going on?

Well it could be one of two things:
One, you could be pregnant and you hcg levels may not be high enough yet. Bleeding in early pregnancy can happen and is normal as long as it is not heavy and not accompanied by cramping. Take HPT in 14 days.
Two, it could be a light period. Every woman experiences irregularity at some point.

2 days late isn't unusual. Being on the same date every month is!

If you are using no form of birth control then you always have a chance of being pregnant. Actually, even if you were using birth control you still have a chance of being pregnant.
Like the other post said, your hcg levels might not be high enough yet to read positive on a hpt. You have to just wait it out and see what happens. If your period doesn't come in the next week or two take another test or go to the doctor and get a blood test done.
