Me and my husband have been ttc and this is our first month , I’m 20 and he’s 25 ,I’m having symptoms such as back pain and some cramps and I’ve been going to the Toliet more often ,I’m late 3 days but I have irregular periods ,my last cycle was 28 days and sometime they are 32,34 depending. I’ve taken 2 test in the last two days and they were negative , but today I had taken another it came up very faint ,like you have to look closely to see it ,is it positive?
