5 weeks and 5 days today

On boxing Day I would have been 5 weeks and 1 day, on this day I had period like cramps in my lower stomach and back on and off all day.

(I went to the drs the next day who has no concerns about eptopic but is getting me booked in for an ultrasound for my pregnancy and kidneys to be check..I'm just very impatient and worried).

The next day they gradually got worse in my lower stomach and back..these past few days I have had period like cramps in my lower stomach each day for around 10 mins (for two of the days the pains were worse on my left side) and then I have nothing for the rest of the day. I don't really have any other symptoms of being pregnant other than tiredness, no period and the odd cramps - I also haven't had any bleeding since I was 4 weeks.

Has anyone else experienced these sort of cramps? I'm worried but trying to stay positive.
