This is our 4th month TTC and the first month we used preseed. My symptoms this month that made me suspect pregnancy was that I actually felt fine. Normally a few days before aunt flow I get cramps and mood swings. The only thing I found odd was that all through the TWW I found myself getting a bit carsick when I was behind the wheel. I also got a heat rash between my BB's 2 days before a positive pregnancy test after going for a 2 mile walk. I have never had a heat rash before so that made me a bit suspicious. Today was my first BFP so i took 3 tests and all had clear positives. Period isn't late until Wednesday, so I am going to test each morning to make sure the line still shows up.
