I have to take progesterone oil injections following a frozen embryos transfer. I am 5 weeks 5 days. And I have to continue my injections till 10 weeks. I do my injections in my thighs so I alternate legs everyday. Last night however when removing the needle the site bleed right away and it sore today. I've had them bleed a little before but not like last night. It drpped all the way down my leg. And now a small bruise.
