BFN - Can I relax and believe Im not pregnant now???

[shoneshine]

have been worrying that Im pregnant the last few weeks, werent as careful as we should of been in the first week of 2009. Periods not back yet as still breastfeeding almost 7m old. Returned at 7m with dd 2 and ds1 aged 4. Have been convinced Im preg as had period type cramps for last fw weeks, shooting pains in boobs, ewcm on during the week of the 'incidents' feeling of pressure on bladder, could that be AF waiting to make an entrance??? Sorry for tmi! Tested with an ebay test today (not morning urine) and only one line. Can I relax???

If you have done a test 19 days after the most recent "incident" and that was neg, then yes you can relax. OK, so sometimes tests are not right but the vast majority of the time they are.
Cramps, EWCM etc can be caused by normal hormones. TBH if you are having repeated patches of cramps and EWCM I would say that you may not be ovulating (i.e. your body keeps gearing up for it and then not doing it) which is what happened to me a lot when I was still breastfeeding.
