Faint BFP on 11 DPO/12 DPO

This cycle I had a terrible UTI and was taking D Mannose to naturally get rid of it around ovulation time. D Mannose has a contraceptive effect and I know this is not a good time to get preggers because I just started a new job on August 1st (maternity leave only kicks in at the 1 year mark) so I was not expecting we had any chance this month (and last month we were in different states).

Anyway, right after ovulation I had symptoms like we had conceived with very sore nipples for a few days (happened with my last chemical) and colostrum was present. However, the symptoms went away around 4/5 DPO and I haven't had any real symptoms since then beyond some sleeplessness and fatigue.

Last night my breasts were sore and I found out a friend got a BFP so I decided to test at 11 DPO with very dilute urine around 9pm. I saw only a vague shadow on the wondfo, which I often see, so thought nothing of it. I went to bed and dreamt I took many positive pregnancy tests. I woke up and then saw a faint line on last night's test. It could be an evap, plus I don't have symptoms. So I took another test though just to confirm, but it too had a shadowy line and as it dried it's a bit darker. Today I am 12 DPO.

Now I know that because they're so faint, I am very likely dealing with another chemical. But I am back to waiting to see if they will get darker or not.

I don't even have a doctor to call since we just moved to a new state, so I am going to just wait it out for now. I don't see any reason to rush and get a beta done since at this stage there's really nothing they can do for me anyway.

My gameplan: I am not going to get excited knowing my track record and the fact that this doesn't look very promising with such faint lines, but I will start treating my body as if I am pregnant....eating good, taking my supplements, no caffeine, and will take my prescription folic acid.
