I'm on Doxy, too. My clinic usually prescribes 1 mg of Zitromax prior to ER, but I'm allergic to Erythromycin so I get to take Doxy for 7 days BID--fun fun. I'm on Estrace BID orally (thank goodness), but I am prescribed the Endometrin TID as well. They've been fine so far, because I've been mostly laying around afterwards. The grossness will be when I have to shoot it up there and then go on my merry way to work. 
If you work, have you gone back yet? I took the whole week off, because last cycle I felt awful up until my 3rd day. This cycle seems to be following suite. I have an acu appointment today at 3pm hoping she can cure my constipation, because colace, gas-x and Phillips MoM are not touching it.
