I think I could be pregnant but I am not sure as the tests I have done are negative. The last period I had was the 23 March and wasn't a regular period as it was on and off for only 2 days when I'm usually on for about 5. I am 2 weeks late on my period now and last night I started spotting but since then nothing, it was also a brown colour. I had been off the pill for 2 months before my pariods started messing up. My belly has bloated and I am tired more than usual these symptoms I had with my first pregnancy. The last test I did was Friday and it came back negative. What's up?
