Hiya
was it blood? Or pink mucus?, I think there is big difference, because the month before I got pregnant I spotted before my period was due, but it really dark spotting, thought it might be implantation but period came on time. Then the next month (ist month ttc), I noticed pink mucus when I wiped, exactly like u said, it comes and goes, I noticed it more in the morning when I first went to the toilet, but then nothing during the day. In fact it was implantation bleeding bout 4 days before my period was due, then I tested the day before it was supposed to come.
So I think theres a big difference, if its spotting but blood spotting, light or dark, I think its maybe just a strange start to a period, but if its only pink mucus and only when u wipe every now and then, expecially if it happens a few times then u actually get nothing the in the days around when ur period is due, i'd bet its implantation bleeding.
Anyway thats my opinion, but the way u describe it, is exactly how it went for me :d , strange huh?
Sending out baby dust if it would be nice surprise to be preggers again!!
