I never had this before. Is there any other explanation for something that seems like implantation bleeding? Can it be part of ovulating? Just a fluke because I'm still messed up and irregular after a MC 3 months ago?

I've had a short cycle for years and I think I ovulate about 7-8 days after AF starts. I've tried temping for the last two cycles but couldn't make any sense of it. I only think this because when I was pregnant before, I started feeling pregnant only 10 days or so after AF. Sore breasts, nausea, cramps (which got worse and worse and then turned into a MC right after AF should have shown), the works!

This month, AF started on June 16 and lasted about 4 days. DH and I were together several times. Then I started to spot again around June 24 (i.e. 8 days later). This lasted for about 3 days and was much lighter than AF. At first I thought I was just having an extra long period, but now I have sore, swollen breasts and occasional cramps. It didn't happen to me last time but that "extra long period" kind of sounds like implantation bleeding--but so early? Is this possible?

What do I do now? If I really am pregnant again, since it happened so fast after my period do I really need to wait until I'm late to test? Whenever "late" is nowadays--I've been pretty irregular for the past few months. It takes at least a month to get an appt with my gynecologist, but should I try to convince the family doctor to prescribe a blood test? I'm scared this will turn into another early loss. I'm also scared that if I don't have "proof" my doctor won't take it seriously.

Also, I'll be leaving Europe for a month and visiting family in the US (I have no health insurance there) just around when I expect to have AF, which complicates things a bit.

I would really appreciate any advice--even just some contact from other people as I stress out!
