I need some experienced ladies

So for the last month I have had every pregnancy symptom mainly throwing up and sore breasts. I waited for my period it was late 4 days then came for 2 days very lightly but my cramps where horrible as normal . Me and my partner are TTC and have been for about 2 months . I don't take any kind of medication to help I want it to be completely natural . 3 out of 6 test didn't show anything the other three were negative I've used the same brand Equate . My belly has perked up and it's very noticeable . I've had this feeling like my skin is being stretched from the inside out . Now I know what your going to say go to the doctor unfortunately my insurance is having complications . Is there any brands you have used that u think work best . And how common is it that u still have your period
