Totally new to this site so apologies for my inability to use acronyms. I have a regular 27 / 28 day cycle - last period was the 1st May and I had unprotected sex on Friday 17th and Sat 18th - I think this falls after when I ovulated (I've not monitored this tho)?? On the Sunday 19th through til the Wednesday 22nd, my nipples were sooooo sore, I had lots of white sticky discharge and I started getting heartburn (I never ever get heartburn!). The heartburns continued on and off (although not so noticeable the last few days). I was expecting my period yesterday (Wednesday 29th) but so far no sign other than more discharge - lighter than before tho. I've been having abdominal cramps for the past 3 days as if I were getting my period but nothing. I did a test yesterday evening and another one mid morning today - both negative. Could I be pregnant or more likely I'm just late for some reason this month??? When should I test again? Any advice / comments would be really helpful!!
