Hi all
Need help from anyone out there that knows about ectopic pregnancies or has experienced one.

Had 1 blasty transferred on 14th Feb, I started to bleed when normal AF would be likely to occur, this started off a lot but only for a day and night then it went quite light. It got quite watery after that with just some red streaks, sometime brown. Nothing overly ugly or abnormal. I had faint HPT positives before the bleeding then started to bleed and stopped doing them. I suspected ectopic before BT was due because I decided to do a HPT just before BT and it was darker than any of the others. Had BT day earlier (day15) because I suspected an ectopic and had a HCG of 38 (not sure about P4).

Then still suspecting ectopic asked to have the next BT early (Monday 1st) so this was 5days after the first, HCG was up to 190 but P4 only 2.6 (probably because of the bleeding).
Now I have to have another BT on Friday. My biggest concern now is that at night, the last couple of nights and even now I have a bit of shoulder pain (one of the signs), ive also had flu like symptoms and lower back ache (also a sign). Could this occur in normal pregnancy?? Ive also been a little light headed at times (could be normal pg or ectopic sign)
Its too early to have a scan and Im slowly going out of my mind. Any help, diagnosis or encouragemnt would be greatly appreciated, thanks.
