Could I be pregnant or just a weird period?

[callaghan88]

So called LMP was the 9th of May, I am not totally convinced though that this was an actual AF as it was not normal like my usual cycles. I usually bleed straight through for 6 days straight, days 1-3 heavy, 4-5 moderate and barely anything day six. Days 1-3 I usually go through 1 and half packs of sanitary towels my flow is so heavy (TMI).
This month :-
Day 1 - pinkish discharge/light bleeding
Day 2 - nothing
Day 3 - Light/moderate bleeding
Day 4 - Nothing
Day 5 - pinkish discharge/light bleeding
Day 6 - Nothing
As you can see I have only actually bled for 3 out of 6 days which is unusual.

PMP- 12/4/13 O - 26/4/13 Bd all that week..

Before bleeding started I felt really pregnant, but most of the symptoms have faded apart from feeling fatique and sick throughout the day. Also last week I had a huge glob of clear discharge which looked rather snot like, But last night I had a huge amount of White CM which was really thick and very stretchy, a lot more stretchy than my usual Ovulation discharge. I had 2 very faint positive HPT's before bleeding not tested again after LMP. Due again next weekend.

Not asking if I am pregnant but if it sounds like a possibility?
