Mastitis - how do I get my supply back up?

My LO is 7 weeks old. I recently got diagnosed with mastitis. I’m on the antibiotics and doing much better now, however, I noticed my supply has dropped! & the last two days I’ve noticed my baby is not content with what my breasts are offering. Luckily I have milk in the freezer to fall back on, however, that is what I’ve been saving to get back to work in the next month. 😕

With that being said can anybody give me any suggestions or advice on increasing my milk supply again. I usually only pump once in the mornings and once at night, while exclusively breastfeeding throughout the day and the evenings. The pumping was strictly for storing. And with those two extra sessions, I was collecting at least 2-3ounces from each breast averaging to a total of 4-6oz being stored. And that was working great keeping my baby fed and supplying enough milk for storage. Now I’m barely collecting past a full ounce on each. Help!
