Good morning!
Sorry to dive right in but am unsure how else to word this?
Me and my partner last had unprotected sex 8 days ago. My period was due a couple of days later, on the 22nd January. A few days ago I had that strange cramp you have just before your period, and as I was about to go to bed I decided to put in a tampon to avoid any ?accidents? in the night, as I have quite a heavy flow. The next morning I woke up and was confused to see that my period hadn?t arrived as expected ? in fact, I?m now six days late. To give you a little background, I was diagnosed with endometriosis two years ago and had an operation on my left ovary, but in the last six months I?ve had barely any symptoms and my periods have been regular as clockwork. I?m eating well, I?m not stressed, and I haven?t lost weight.
Although it is probably far too early to take a test, I bought a pack of two tests yesterday. The first one was negative...
... but still my period doesn?t come ? although my boobs have grown, which is always a bonus 
Could I be pregnant?
