I nursed DD1 until a few weeks ago, through my pregnancy with DD2 and almost a year tandem. I remember my nipples being sore again with DD2, but not nearly as sensitive as with DD1. It is tough getting used to a smaller mouth again and a different suck. I did love having a toddler help with engorgement and with clogged ducts. It was not nearly as bad as the first time, but I still used lanolin and aired them out to prevent cracking and chapping. I am sure other's have different stories to tell.
So, I have been feeling all sorts of fertility signs since DD1 weaned, and I took a test today (I have a bunch of the dollar world ones stored up). The test I took seemed to be invalid as it had pink horizontal streaking.... I took a second test and there is a white line where the test line should be and thin pink stripes on either side. It reminds me of a STARK negative test.... I really didn't expect anything different, but still always hoping.
I didn't get my cycle back till about 13 months with DD1 and didn't ovulate until 16 months and got my BFP the next month. I just really don't want to be pregnant in the summer (live somewhere REALLY hot in the summer and will have 2 active kids wanting to play outside....)
