I'm not as worried about it now, however it was a really big clot. Still not sure if I should see the doctor, as I didn't keep it... Photos and description still might help. Last month I had to have the MMR(measles, mumps, rubella) vaccination for uni prac placement, and we did a pg then (coz she couldn't give it to me if I was pg, and was told that not to try until after 3 months of the vaccine). The test was negative. However, it could have been too early, or maybe afterwards - coz accidents do happen! We aren't trying - at all.
