BFP Finally After 2 MC!

Finally got my BFP, actually got it last week but only just felt brave enough to post.

had 2 mc before dd. Been TTC for just over 2 years now. In that time, after ttc 10 months, had mc at 13w. Then after another 6 mth had BFP but it only lasted 5 days. Since August 11, been having tests for recurrent mc and generally going insane. no problems have shown up and dr told us to go away, enjoy xmas and stop being so stressed about it. easier said than done.

So, this time, I was not hopeful at all, drank lots of wine before and during 2 ww, did intensive exercise and had bad fall, was not particularly careful as was convinced it would not work and would end up starting IVF in a few month time.

2 dpo - sore left boob started (but I get that most months before AF).
8 dpo - felt bloated and mildly constipated (which I never get but had in previous pregnancy). really thought nothing of it though. not like the implantation pain I think I have felt before.
9 dpo - BFN- think about now both boobs a little bit sore but thought nothing.
10 dpo - BFN
11 dpo - BFN (or so I thought) vague dull ache. convinced AF coming. boobs feeling a bit sore. glum.
12 dpo - BFN (tested last thing at night), told hubby it was definitely not happening and both upset. mild dull ache again. boobs bit sore but totally convinced just pre-menstrual symptom. glum.
13 DPO - in the morning, for some weird reason, dug out my BFN from 11dpo, had not thrown it out and there were 2 lines, frantically researched evap lines but this one was def pink not like an evap line! I think I was so upset the line had not appeared right away with the control line and was annoyed I had wasted yet another test, I had not waited long enough. so, quickly did CB digital test and got another BFP! still dull ache. convinced it won't last the day. that was one week ago.

Since then, had mild ache in lower ab on and off, faint pulling feeling and sore boobs on and off but I know I am actively looking for any slight feeling now.

what did we do differently?
didn't hold back on the drinking! had a good xmas, drank without going OTT, relaxed and had fun.
started up my exercise class again.
stopped using pre-seed. seemed to irritate me and affect cm.
genuinely did not get my hopes up, focused on our plan B.
dr has now put me on low dose aspirin and progesterone supplements (since BFP).

That's it, just hoping this one is a healthy bean!
