BFP After 5 Months and 1 Chemical

I am still in shock that we are expecting baby number 2 - Due Feb 25 (Exactly 2 years to the date I was due with number 1!!) I stopped breastfeeding in January and came off the mini pill so we decided to start trying again. In April I got a positive pregnancy test then 2 days later it was negative and I started bleeding (chemical). I was devastated. This month got another BFP and I feel much different about this one! Things we tried differently this month: Pre-Seed, I drank tea (Yogi brand called "Women's Energy), Mucinex, took B-2, ate a lot of pineapple after ovulation. Period is due tomorrow, and have had no spotting (I had a lot of spotting in April and felt something might be off) and two very dark pregnancy test lines! The lines in April never got dark. I ovulated on June 1st. We BD on: May 29, 31 and June 1, 2 and 4. Here are my symptoms:
1 DPO: Heavy feeling in uterus
2 DPO: cramping very low in middle of abdomen
3 DPO: nothing
4 DPO: light cramping
5 DPO: nothing
6 DPO: light cramping
7 DPO: headache
8 DPO: nothing
9 DPO: light cramping
10 DPO: dull period like cramping, backache
11 DPO: period like cramping again - first BFP! Faint but there. Already darker than when I had the chemical
12 DPO: took 3 more tests - all very dark!!!

So so excited. Praying this one sticks!!!!!! Baby dust to you all!!!
